How To Use VCV UTAU Voicebanks

Introduction to VCV UTAU

Though the UTAU software was initially designed to process CV voicebanks, the UTAU community, over time, began to experiment and construct new recording methods. One such technique that developed was referred to as “triphones”, “triphonics”, or 連続音 ( renzokuon ). The approach would later be popularly referred to as VCV, or “Vowel-Consonant-Vowel”. VCV was the second major recording method created by the UTAU community, and it soon became one of the most popular and widely adopted. It is commonly associated with multipitch voicebanks (a UTAU recorded with multiple voicebanks at multiple pitches) to obtain even greater realism.

A triphone or triphonic is a sound consisting of three basic phonemes. Phonemes are a distinct unit of sound used in language, such as “k” “d” “p”. VCV utilizes triphones to create a smoother, more lifelike vocal than CV by “stringing” three phonemes together. So, within VCV, a triphone would look something like “a ka”. So long as the voicebank has a high-quality OTO, UTAU will blend together the starting and ending vowels of one note into the next, creating a fluid voice.

Numerous members of the community will argue for and against VCV’s ease of use. Many claim recording and configuring VCV is more difficult and time-consuming than VCV, but that it is more straightforward to utilize and, ultimately, procures a better sound.

Using VCV

Let’s learn how to use VCV in UTAU! First, load up the desired Voicebank and UST file (if you have one). There are two scenarios here: the UST is either formatted for VCV or it just isn’t. Not every UST comes in VCV format, but you may really, really want to use the UST. Fear not, there are many options to remedy this situation!

The tedious method that we aren’t going to actually consider a method, but rather a painful last resort: Add the preceding vowel to the lyric: Let’s say you have two notes “か” (ka) and “あ” (a). Simply add an “a” in the same note as あ. Simply, あ now becomes “a あ”.

The easiest method (that, unfortunately, costs money): UTAU Shareware: If you have the shareware version of UTAU, you can simply hit the auto VCV button, and UTAU will turn the vowels into VCV!

Other methods: Plugins: Some plugins may convert the CV vowels into VCV without altering the rest. Others may turn the entire UST into VCV. Experimentation is key! IroIro is our favorite recommendation, as the plugin has many other useful features packed into it as well.

Navigating to your installed UTAU plugins

If you have IroIro Installed, follow Tools > Plug-Ins(N) > IroIro. Select CV -> VCV and click OK.

Once your UST is in VCV format, you are ready to proceed.

Fitting a UST to a VCV Voicebank

Fitting a UST file to a UTAU Voicebank will definitely improve the sound and make your covers appear more professional. By fitting the UST, you are telling the software to conform to that particular UTAU’s configurations and setup (OTO). This is an important step if the UST was not explicitly made for the UTAU you are using, and it helps to improve the fluidity and clarity of the voice. So, let’s do it!

To start:

Open a UST file
Select all (Ctrl+A)
Right-click on a note
On the pop-up, select “Property” or “Region Property” (if you selected all notes). A new window will appear.
You may notice sections on this window labeled “Preutterance” and “Overlap”. To their right, there is a “Clear” button. We want to click that.
Next, at the bottom of the window, there is a box labeled STP.
1. If it has a value, delete it.
2. If the box is grayed out, double-click the box to clear it.
Press “OK”
In the top right of the main window of UTAU, you will see a group of four buttons (ACPT, P2P3, P1P4, RESET).
1. Click RESET
2. Then click P2P3
3. Next, P1P4
4. P2P3 again
5. Click ACPT (You can click this multiple times if you see any red “!”, and it may take care of those. More on that in just a second!)
That’s it! You’ve fit the UST to your VCV Voicebank

Special Characters, Envelope Issues and Other Problem Samples

Special Characters

While fitting a UST to your UTAU, you may find errors highlighted as red “!” along the way. VCV is a popular method and widely employed, so a user may run across custom notes, properties, and expressions within a UST. Your UTAU may not have these special notes and sounds, so, we need to run through a few options.

Manual removal
1. Simply edit each note, one by one, and delete the extra symbols.
SuffixBroker (for custom characters at the end of a note such as an up or down arrow, a number, or another special symbol)
1. Select the notes you want the characters removed from
3. Found under: Tools > Built-in Tools > SuffixBroker
5. Leave the box blank, click OK, and now the Suffixes are gone! PLEASE NOTE: this does not always perform 100%. Make sure to double-check your work.
Third-Party Plugins

Much better!

Envelope Issues

How to use UTAU VCV Voicebanks: editing envelopes

The error still shows up, and, more confusingly, the sound sample exists and your oto is fine. Grr… Now that’s frustrating! But we have a fix. Let’s check and edit some envelopes!

Very carefully, right-click on the note. A new pop-up will appear. Hover down to “Envelope…” and click on it.

And…

YIKES! That’s pretty bad! Worry not, there’s a simple fix. Let’s click “Normal”. 9/10 times, that does the job.

If the error still persists after hitting “Normal”, simply drag the red boxes around until they look, well, normal. Click OK and it should be good to go!

Much better, and now our “!” is gone. We are ready to tune and mix!

Setting Up Multipitch, Multiexpression Voicebanks in OpenUTAU

Introduction to Multipitch, Multiexpression Voicebanks in OpenUTAU (as of January 2022)

Before We Begin

This tutorial is a bit much, and it acts as Part One to our Voice Colors blog! Today, we want to go over how to set up Multipitch, Multiexpression voicebanks in OpenUTAU. The tutorial assumes you understand the following:

How Multipitch voicebanks work in UTAU
How to use and set up a Prefix.map
Suffixes and Prefixes, and how to use them to create Multipitch

This tutorial also assumes:

You have operational voicebanks prepared
All of your pitches and expressions, for each voicebank, have a different suffix

Lastly, we are not experts! We are learning along with our community. There may be more than one way to perform the following steps, and things may change in the future as OpenUTAU develops. We will do our best to keep this blog as up-to-date as we can, and we will come back to make edits when necessary. Knowing that, let’s dive in!

Getting Started

We know now that it’s possible to set up Multipitch, Multiexpression Voicebanks in OpenUTAU. Today, let’s go a step further and use our knowledge about Voice Colors and PrefixMaps. Let’s get into the nitty-gritty and set up something a little more complex!

For this example, I will be porting over an existing UTAU with five different appends/expressions. As this is not a STUDIO OGIEN created UTAU, we will be redacting the name to avoid confusion. We do not manage or act as user support for this voice, and the following tutorial is only for educational purposes. Now, let’s set this up!

To start, I have downloaded all 5 expressions as well as organized and extracted them on my Desktop. For the sake of sanity, I have also prepared six new folders for extra samples to help keep organized during the process. Make sure to keep the original compressed files as a backup, just in case.

Multipitch, Multiexpression Voicebanks in Open

Let’s begin inside Voice 1’s folder. I have Voice 1_extras open alongside it. Let’s delete the $read. Next, if you have breaths and other samples, let’s sort them into the _extras folder for now.

Alright, now that we have cleaned up, we are left with the following three folders, each containing a unique pitch.

For the sake of organization, let’s rename these folders. For this example, I will name this Voice 1_[original folder name]. Go ahead and repeat these steps with the next expressions.

Finding Pitches For Mystery Files And Unsorted Folders

As I began to clean up Voice 2’s folder, I noticed a small situation. We have a bit of a dilemma on our hands!

One of the pitches for Voice 2 is in the main directory, it hasn’t been labeled with the pitch’s name, and there is no Suffix in the oto.ini. If this is your own UTAU, and you know what the pitch is, go ahead and throw these samples into their own labeled folder. If this is not your UTAU, make sure you check the readme files provided to figure out the pitch. However, let’s say there was no documentation to help. We can still find the pitch, even if we’re not musically inclined. I will show you how to find the pitch using REAPER!

After opening, drag and drop a sample into the track. To understand what pitch this sample was recorded on, I’m going to add an FX to the track called ReaTune.

Hit OK, and you will see a new window pop up. Play the track and watch REAPER works its magic.

The pitch will waver, so pay attention and try to find the average. If you can also find documentation on the voicebank, that will help a lot as well. Create a new folder with the pitch’s name, and move the voice files into it. Let’s proceed!

What To Do With Unique Samples and Other Files

What do we do with our extras, now that our folders are set up? Well, that depends, and it can be done in many different ways. For this particular Multiexpression OpenUTAU voice, I’m going to put in a little more manual effort to make sure these notes always work.

Let’s open Voice 1_extras back up alongside Voice 1.

We want to still save the readme files, the character file, and the icon to merge together later on. For now, I will leave those in this folder. However, for the voice samples, it’s a little more complicated. In this example, the extras are recorded for only one pitch. Normally, these would be useable in regular UTAU, but with the nature of these Multiexpression OpenUTAU configurations, we need to define them more clearly for the program to understand what’s going on. So, gather your Suffixes and get ready to copy-paste, and copy-paste a lot at that.

Inside the oto.ini, we can see the extras lack a Suffix. That’s fine, as one pitch in this particular expression does as well. For that, we will copy paste the voice files into said folder. Once copied over, open the oto.ini file within that folder, and copy+paste the lines for your extras within. Now, this pitch knows how to use these samples.

For the next pitch, you will have to add the suffix in by hand. Once you’ve added in the suffix, copy and paste those oto lines into the oto for the next pitch. Example:

Copy and paste the extras into the folder. For the next pitch, just hit Ctrl H to bring up Notepad’s search and replace. Just be careful what you put into it. Always double check your work!

Configure the rest of the extras and we can proceed!

Putting It Together With Voice Colors

Now that our files are ready, let’s move them into a brand new folder. Create a new folder, this one you can name whatever you please. For this example, I will call it “VOICE_Master”. VOICE_Master will need a few special files.

First, let’s gather all the readmes, character files and icons. Decide what icon you would like to use, and set up the character.txt accordingly. Update the name, author, image, web, etc. as you see fit. Next, it would be best to label each readme to refer to the proper voicebank, or combine them all into one. Once finished, you will want to place these within the VOICE_Master folder.

Next, it’s time to place each pitch into the main directory. PLEASE NOTE: You must place individual pitches into the main directory. Splitting the pitches up by expression (ex: VOICE_Master/Voice 1/1_G3) will not work, and OpenUTAU will split the expressions up. Rather, you want your setup to mimic the one below:

Let’s compress this bad boy and import it into OpenUTAU!

SUCCESS! The files are recognized as one voicebank. Exactly what we need for part two.

From here, you can follow our tutorial on OpenUTAU voice colors to achieve the desired effect.

Setting Up Voice Colors in OpenUTAU

About OpenUTAU’s Voice Colors

Voice Colors (also referred to as subbanks) are an exciting new direction for the OpenUTAU software, improving upon the usage and development of multi-expression voicebanks. Until now, users of UTAU have had a strict way to go about using Appends. For a monopitch voicebank with the additional expressions added in, creators of UTAU voices could configure appends with suffixes. Users could then plug the suffixes into the SuffixBroker within the software, or manually add the suffix to each note to achieve the desired effect. For example, a “Soft” append may include the suffix “S”, users would then add this letter onto the end of a note to make the software play that notes for that specific append.

The Old Way

To achieve a multi-pitch, multi-expression voice, creators would have to either split up each append (ex: soft, power, and the base voice all released and used separately) OR the creator of the voicebank would have to use the same pitches for each expression to be able to use all three voicebanks at the same time (ex: all pitches of soft, power and the base voice would all be recorded at A3, C4, C5). Such an example is our very own KASAI OG01 SALIENT voicebank.

These issues add difficulty when developing new voicebanks, as many voice providers find it difficult to keep the same range for such different tones of voice. Luckily, we no longer have either of those problems with OpenUTAU Voice Colors. Essentially, every Color can have its own, unique prefix-map. In short, this gives users the ability to assign different ranges and suffixes to different voicebanks.

An Example

Let’s say a voicebank includes three appends; Soft, Power, and Base. Let’s also assume each of these voicebanks has three pitches, but they all use a different set. Soft might use F3, A3, C4. The base may use A3, D4, and F4. Meanwhile, Power might include G3, E4, and A4. That’s very complicated and pretty much impossible to use together in UTAU. Some samples would be used on totally different ranges than they were meant to be used for, causing a rather chaotic sound. In this scenario, within UTAU, it’s better just to split these voices up to use individually.

HOWEVER, with OpenUTAU’s Voice Colors, we can now assign all three appends to their correct ranges. Soft can use F3, A3, and C4 where they are meant to be used, and the same goes with the other two.

OpenUTAU Voice Colors Tutorial — An Example of Defined Voice Colors

The New Way

In comes OpenUTAU’s Voice Color feature! A handy new tool that gives UTAU creators a greater scope of diversification for their expressions and range. The Voice Color feature is essentially the SuffixBroker’s natural evolution, becoming more and more like commercial vocal synthesis products. Users no longer have to plug Suffixes in individually or through a series of menus. Rather, simply make sure “CLR” is available to use at the bottom of a track, and make sure you are using a UTAU configured for Voice Colors. If not, we’ll teach you how to set that up in just a minute.

Okay, so what makes this so great? Just how easy is it to use? Well, that’s a simple question with a simple answer. By just the press of a button, or a click and drag, users can quickly and easily alter numerous suffixes at the same time. No more rooting around in readme files to copy and paste special characters!

Awesome, how fun! Now we have greater flexibility than ever before to develop interesting and unique voicebanks. However, as OpenUTAU is still very fresh and new, it is going to have some issues as it continues to evolve. One such issue is setting up Voice Colors themselves. There’s not a lot of documentation or help just yet on that, so setting OpenUTAU’s Voice Colors up? A little tricky.

Setting Up Voice Colors in OpenUTAU

Let’s go through the process of setting up Voice Colors! The developers behind OpenUTAU have made this process pretty darn easy. Today, I am working on porting over APOLLO OG0X, so she will be the voicebank used in this example. Let’s go to Tools > Singers.

Ah, here we are in the lovely Singers window. Here, we can see a list of all our subbanks, their aliases, Sets (folders), sample names, phonetics, and prefixes. Extend the window out to see even more information!

Let’s set up some Voice Colors. Go ahead and click “Edit Subbanks”.

Alright, here’s where the magic happens, and things get a little tricky. APOLLO OG0X’s VCV includes three voicebanks. Original, Breaking, and Murmur. Let’s set those up, so I can show you an issue you may stumble upon. Click “Add Color” and enter the name you wish. I’ll start with “Original”, her default singing voice.

This one is a super easy monopitch voicebank, as it has no suffixes or prefixes. Simply hit save.

Boom. Done. One color down. Now, let’s set up an append. Click “Add Color”, and name the append like before. Now, grab the suffix used in the oto.ini for this specific voicebank. Hit “Select All”, add the Suffix into the Suffix box, and hit “Set”.

Looks good. Hit save and repeat for all appends.

Voice Color Issues

All right, everything looks good, now let’s test it!

Ah… Uhm… Remember that tricky bit I mentioned beforehand? Yeah, this is it. As OpenUTAU is still in the early stages of development, it’s going to have some little bugs here and there. Notice how “Breaking”, APOLLO OG0X’s power bank, doesn’t assign her suffix to the note? At this time, on January 18th, 2022, OpenUTAU prioritizes Voice Colors alphanumerically. If the name of the default voicebank comes after the name of an append in the English alphabet, OpenUTAU assumes it is the default voice and won’t add a Suffix. This is just a simple override issue that may change!

For now, let me show you a quick, easy fix. Go back through Singers > Select the UTAU > Edit Subbanks. For this instance, I’m selecting Original.

Simply hit “Rename”, and give it a name that, alphabetically, comes before the names of any append. For this example, I chose “Base”. I’ve also seen others simply use quotes (“”), which also works. Click “OK” and then “Save”. Go back to your track to check….

There we go, all fixed! So long as the default voice has a name that comes first alphanumerically, it will stick to the bottom of the Voice Colors list and should function properly. As OpenUTAU develops, this trick may become unnecessary, but, for now, it is here to help, and so are we!

A Quick Tip

You set up your voice colors, you tested them and they worked, but when you loaded a UST… What the heck!? Why aren’t they working!?

Here’s a nice quick fix. You may notice the UST imported in this example is in VCV format. Hit Ctrl + A to select all. Go to Lyrics > Japanese VCV to CV. This will turn the UST back to CV, and OpenUTAU will automatically convert the notes into VCV as seen below. We have only tested this with VCV voicebanks at the moment, so if you are employing a different method, you may need to experiment!

LET’S HAVE FUN WITH VOICE COLORS!

How to Use KASAI OG01 Original CV-V

PENDING UPDATES, THIS ENTRY IS CURRENTLY OUT OF DATE!

Introduction to KASAI OG01 Original CV-V

KASAI OG01 “Original” is a CV-V style Voicebank developed by STUDIO OGIEN. KASAI OG01 was originally developed back in 2009, though she would not be released until 2014. We created her first Voicebank as a CV to mimic the era, though we did throw in some special samples to improve her clarity and smoothness. KASAI OG01 is, essentially, a Multipitch CV Voicebank with additional VCV formatted vowels (though her CV vowels also work just fine!). This reduces her choppiness, makes her easy to use for newcomers, and acts as a step to introduce beginners to VCV.

Using CV

CV Voicebanks are perhaps the easiest to use and record, and they are a great starting point for any beginner to UTAU. For the most part, you can import a UST file into UTAU, select a CV Voicebank, and hit play. However, for the sake of a better sound, many with experience in the software may tell you to “fit” the UST.

Fitting a UST file to a UTAU Voicebank will definitely improve the sound and make your covers sound more professional. By fitting the UST, you are telling the software to conform to that particular UTAU’s configurations and setup (OTO). This is an important step if the UST was not explicitly made for the UTAU you are using, and it helps to improve the smoothness and clarity of the voice. So, let’s do it!

Fitting a UST to a CV Voicebank

Open a UST file
Select all (Ctrl+A)
Right-click on a note
On the pop-up, select “Property”. A new window will appear.

You may notice sections on this window labeled “Preutterance” and “Overlap”. To their right, there is a “Clear” button. We want to click that.
Next, at the bottom of the window, there is a box labeled STP.
1. If it has a value, delete it.
2. If the box is grayed out, double-click the box to clear it.
Press “OK”

In the top right of the main window of UTAU, you will see a group of four buttons (ACPT, P2P3, P1P4, RESET).
1. Click RESET
2. Click P2P3
That’s it! You’ve fit the UST to your CV Voicebank

Using CV-V

CV-V may sound a tad intimidating, but for KASAI OG01 Original, it is an optional feature. STUDIO OGIEN’s version of CV-V simply refers to a CV Voicebank with pure vowel recordings in VCV format added in. How do we use them? Let’s take a look.

The simplest method: Add the preceding vowel to the lyric: Let’s say you have two notes “か” (ka) and “あ” (a). Simply add an “a” in the same note as あ. Simply, あ now becomes “a あ”.

The easiest method (that, unfortunately, costs money): UTAU Shareware: If you have the shareware version of UTAU, you can simply hit the auto VCV button, and UTAU will turn the vowels into VCV!

Other methods: Plugins: Some plugins may convert the CV vowels into VCV without altering the rest. Others may turn the entire UST into VCV. Experimentation is key!

Using Multipitch

We configured it for you, so you don’t need to do anything special. Just don’t delete the Prefix Map file!

Troubleshooting

How to Use CV UTAU Voicebanks

Introduction to CV UTAU

Those who are new to UTAU may find the idea of Voicebanks a little confusing. VOCALOID standardizes its voices, making utilization simple. VOCALOIDs recorded in specific languages essentially function the same, making the inter-usage of assets a breeze. Since UTAU is a community-based tool, many different styles and techniques have been invented over the years. In short, standardizing UTAU is pretty much impossible, making the learning curve a bit more intense.

The first Voicebank style invented for UTAU was “CV” (known as 単独音 tandokuon by Japanese users), or “Consonant-Vowel” style recordings back in 2008. Phonemes (smallest unit of speech distinguishing one word from another) in the Japanese language are rather simple, usually consisting of one consonant and one vowel. You may hear the phrase “Diphones” used when referring to CV Voicebanks. CV uses two phonemes for each sound in its library.

However, with its strong points come its downfalls. CV tends to be “choppy” and more robotic than more complex styles like CVVC, VCV, and VCCV. Still, it is where most users suggest starting out when recording and using the software, and many senior members of the community still utilize this recording method.

Romaji vs Hiragana

Before we begin, we need to establish a very important difference between Voicebanks! Depending on where the Voicebank was developed, it may be written in Romaji or Hiragana. Taught to children, Hiragana is the most basic style of the Japanese alphabet, and it is mostly written in diphones. It is a phonetic lettering system, meaning the symbols portray sounds rather than words. The word hiragana literally means “ordinary” or “simple”. Romaji is a phrase used to refer to the Romanization of Japanese words and sounds.

So, how does that pertain to UTAU? Simply, a Japanese UTAU Voicebank can be written in either style and so can a UST. See where this is going? If the styles don’t match up, your UTAU won’t make any sound. How do we fix this without manually fixing every note?

There are a few different ways, but let’s go with the easiest option. Plugins can handle a lot of these issues, and we have a few personal favorites on our OGIEN UTAU Suite page. Head on over to the page and download iroiro, a plugin that can actually convert the UST to Hiragana or Romaji. Follow the instructions for iroiro’s installation and you should be ready to go!

1. Click RESET
2. Click P2P3
That’s it! You’ve fit the UST to your CV Voicebank

One final tip for optimal smoothness: Crossfades.

The Crossfade function crosses the envelopes of a vowel sound and the preceding one as well. To use crossfading in your UST:

Select the notes
Go to Tools, then Built in Tools
Select Crossfade
Finally, press OK

Download and Install UTAU

Hi everyone!

Today, I will be going over the process of how to download and install the UTAU software onto your computer. This will be a learning experience for all of us! I have no idea what I’m doing, but Ceren is here to help me along the way, and I can help teach you all how to properly install the software without a hitch! (Well, there may be a hitch, but I won’t tell you about that…)

Changing Your System Locale

So, we need to do this thing in order to properly run the UTAU software. Before you try to skip this step, your UTAU software will read in gibberish when opened without doing this step. I know, we just wanna get to the fun stuff, but we have to do this for the ship to have smooth sailing.

What does changing your system locale mean? All it means is that we are changing the locale for non-Unicode programs (I don’t know man, I’m just a writer. After some googling it appears that it’s just a term for readable character data.) from English to Japanese.

If your PC doesn’t have Japanese already installed, head over to your Settings, select Language, then Add a Language. From this point, type Japanese into the pop-up box, select it, and hit the Next button. Next, deselect the “Set as my Windows display language” unless you wanna roll like that. You do you boo! But, if you want to keep your display language English, deselect that option. Last but not least, click that Install button!

Let’s actually change your system locale (for Windows)!

Open the Control Panel
Select the “Clock, Language, and Region” option
Select “Region and Language”
A window should pop up. Select the tab that is labeled “Administrative”
Select “Change System Locale”
A dropdown list will appear. Scroll until you find Japanese, then select it.

BOOM SHAKA LAKA! UTAU should now be able to read UST’s correctly!

Have concerns? No worries, I did too. Changing the System Locale will affect how your backslash (\) is displayed, causing it to look like a yen symbol in some programs. I mean, it’s not like I use that in my writing or anything…..But, I digress; let’s move on.

Time to Download the UTAU Program

Now that our system can now register Japanese, let’s download the software! I don’t know about you guys, but I don’t understand much Japanese. Throw some French at me, then maybe. Anyways, we need to head over to this lovely website: http://utau2008.xrea.jp/, which will lead you directly to download the software.

When you get to the website, there will be some links followed by Japanese text. All you need to do is click the link that says v0.(latest version number) zipアーカイブ. This will launch a zip file, which you can unzip in your desired location on your computer.

This will open the fully operational version of the UTAU software. However, it will be entirely in Japanese. As I said earlier, I can no read that. How can this be fixed? There is an English patch available for us Western fans to utilize, which can be found here: http://utau.wikia.com/wiki/UTAU_wiki:UTAU_GUI_Translation.

We need to create a new folder within the UTAU(version number) folder you have with this patch. Create a new folder and name it “res.” Once this is done, unzip the English patch file into this new “res” folder.

We Made It!

That’s…that’s it. We did it! We all now have a fully functional version of English UTAU to create new UTAUloids and make songs!

As a note of caution: if you try to pull the UTAU icon out of the folder and launch it, it will run in the default Japanese language. To stop this from happening, you need to keep the icon with the English patch in the folder. If you want to launch via the program icon, you can drag the icon to the taskbar/dock of Windows or go into the UTAU folder and click the icon there.

What is OpenUTAU?

About OpenUTAU

OpenUTAU is an open-source project created by StAkira, meant to improve upon the original editing environment for the UTAU software. The software provides a modern user experience, building upon the initial concepts originally introduced in UTAU. As an open-source program, it is available on GitHub. Contributors can assist in the development of this exciting new engine. Many other developers have contributed parts as well at this time, aiming to create a true community UTAU tool!

Editor — *Preview of OpenUTAU from the project’s page*

What OpenUTAU Is Striving To Be

Above all, the main focus of the OpenUTAU project is to create a modern UTAU user experience without replicating exact UTAU features. Certainly, it is planned to boast an easy-to-use plugin system, a smooth preview/rendering experience, an efficient sample connecting engine (wavetool), and an improved resampling engine interface.

OpenUTAU aims to grant a few of the UTAU community’s long-held wishes as well, bringing it up to speed with more advanced programs. It will feature select compatibility with UTAU technologies, including intelligent VCV and CVVC. The program will automatically convert CV to VCV. If a VCV sample isn’t available in the voicebank, it will fall default to CV.

Additionally, perhaps the most exciting feature, Internationalization, will include UI translation and file system encoding support! What does this mean? In short, you should prepare for an easier user experience. Complex languages in UTAU, such as Arpasing English, will be easier to use than ever. Forget [l ih v], just enter “live”! The software does the rest. At this time, select languages and voicebank styles are compatible with this technology.

Currently, OpenUTAU presents a rather transparent operation that aims to keep the user in the loop. In addition to a Discord server for users and developers, the engine notifies the user with update notifications. These updates install directly from within OpenUTAU. All in all, the software appears to be on its way to a more powerful, community-based tool that UTAU fans have been wishing for. We are excited to see where it goes!

OpenUTAU automatically checks for updates on launch!

What It Is NOT

At this time, it appears the scope of OpenUTAU does not include its own resampling engines (a.k.a resampler), a full-featured digital music workstation (ex: mixing and mastering), nor does OpenUtau intend to be a Vocaloid duplicate (save a few similar features).

You Could Help Shape The Future Of OpenUTAU!

As open-source software, OpenUTAU was literally made to be a community endeavor! Developers across the globe are able to contribute and improve upon the project. Currently, users can report issues through Discord or Github directly to the creators. For those with skills in coding, contribute fixes through pull requests! The team has also set up a Trello board to see the engine’s progress.

What Is UTAU? A Brief Overview

UTAU is a Japanese singing synthesizer application created by Ameya/Ayame. This program is similar to Vocaloid, a professional vocal synthesis software that would inspire UTAU’s creation. Furthermore, UTAU is an independent application that is free for anyone to download and use (there is also a shareware version with special features available, but the free version on its own is already perfectly solid). The program uses .wav files the user provides to create a singing voice, which will synthesize by introducing song lyrics and melody.

UTAU, like Vocaloid, presents the user with a piano roll. Additionally, users can input notes/midis/etc. into the software, add lyrics, and tune the vocal to create a semi-realistic singer, more commonly referred to as a voicebank. Moreover, each Voicebank is unique, with its own strengths, weaknesses, voice type, range, and terms of use.

UTAUloids Rise To Fame

UTAUloids have been on the rise since the shareware’s release in 2008. Certainly, the most notable faces of the program are Defoko and Kasane Teto. Defoko being the built-in voice for the UTAU shareware, while Teto is the ‘face’ of UTAU. They both have immense popularity. A small fun fact: new Vocaloid fans often mistake Teto as an official Vocaloid voicebank! Check out their voicebanks in action below.

How Does It Work?

First off, we’re glad that you’re excited to jump into creating your first Voicebank, but there are a few things you need to know first!

Programs to Create Voicebanks

Fl Studio: A DAW (Digital Audio Workstation) used within the UTAU and Vocaloid communities for many years. It’s most used by these communities to mix songs/covers.

Audacity: A free-to-use DAW. It is typically used to record and splice voicebank samples.

Reaper: A popular DAW that offers a free trial period. Often used to mix songs and is rather user-friendly.

OREMO: A free-to-use program created specifically for recording Voicebanks. This program is a fan favorite for recording since it will automatically name a user’s voice samples as well as add aliases to the file name. Features a metronome and BGM function to keep recordings on time and on the tune.

setParam: Another program created specifically for use with UTAU, specifically OTO configuration. While UTAU possesses an interface for configuring OTOs, setParam offers a more intuitive interface and allows the user a much more detailed look at their recordings.

MIDI: (Musical Instrument Digital Interface) Often used in music production, it is a standard file format for communicating information between musical instruments. MIDIs can be used in the creation of UST files.

Resampler: A vital component of UTAU. This engine reads a Voicebank’s WAV files when the user plays a track in UTAU or when they render it for external use.

FRQ: Files generated by the resampler to properly read the Voicebank’s WAV samples. If you download a Voicebank that has FRQ files in it, don’t delete them! The creator may have edited them manually to fix errors and glitches in the Voicebank.

Voicebank Types:

CV: “Consonant Vowel” recording format. The smallest and simplest style of Voicebank, this is a great choice for beginners to get acquainted with the recording process.

VCV: “Vowel Consonant Vowel”, blends together the ending vowel of a sample with the consonant-vowel pair of the next. While it is more labor intensive to create compared to a CV bank, it’s the most popular form of Voicebank for its smooth end result.

Lite VCV: A simplified/compact version of a VCV Voicebank with more smoothness than CV. A good option for those wanting to branch into VCV.

CVVC: A CV Voicebank with “VC” samples to improve clarity and smoothness. Easier to record than VCV, but trickier to properly configure. This recording style can offer more flexibility than VCV, depending on the Voicebank.

Voicebank Styles:

VCCV: Developed by Cz, one may refer to this as the new standard for English UTAU Voicebanks. Widely supported by the community and praised for its clarity, though it does create an Americanized accent in a lot of Voicebanks.

Rentan: A recording style specific to CV Voicebanks. Samples are recorded all at once, rather than one at a time, within the same file. After being configured in UTAU, it works just the same as a standard CV voicebank.

Multipitch: A style of Voicebank that uses multiple single voicebanks, all recorded at different pitches, into one larger Voicebank. Allows for a much greater vocal range with a more natural sound.

Kire/Powerscale: A Voicebank type where, as the voice reaches higher pitches, the recordings become more powerful. Popular in the community and useful for Rock songs.

Appends: A term originally derived from Vocaloid (specifically, Crypton Future Media Vocaloids). These Voicebanks are recorded to fit a specific theme or timbre. Examples might be “Soft”, “Whisper”, “Power”, “Dark”, etc. Commonly recorded as stand-alone Voicebanks, but may also be included in Multipitch/Multi Expression voices.

Terms To Know For Post Production

Mora: The number of syllables in a voice sample. For example, “a-a-i-a-u-e-a” is a 7-mora style recording.

Prefix map: An important file for Multipitch Voicebanks, this is how UTAU knows what voice samples to play on which notes.

Tuning: In which the user warps, bends, and/or changes the pitch of a voice track in a Vocal Synthesis software. This is done to change the way the voice sings a song in order to make it more unique or more human-like.

Consonant Velocity: A configuration in UTAU that can be changed per track or single note. This affects how quickly the consonant part of the voice sample plays. Usually, this is used to avoid a “slurring” sound in playback for quicker songs.

Flags: Codes used by the Resampler to alter the voice properties of the UTAU. They can be used to add breathiness to a voice, reduce nasal tones, make the voice sound more masculine/feminine, and much, much more. The Flags are typically defined per Resampler, so some may offer different effects than others.

Alias: A name given to voice samples in the OTO. This tool can be used to assign multiple names to the same recording, which is commonly used in VCV banks.

Mixing: The process of taking vocal tracks and combining them with an instrumental in a pleasing way.

File Types

.WAV: The file format UTAU voice samples are recorded in. WAV is the only file type UTAU will use for a Voicebank on Windows computers.

.UST: UTAU Sequence Text Files. Similar to sheet music or a MIDI file (which can be turned into a UST), this is the main file type used in UTAU to store information about a voice track.

OTO: Also known as an oto.ini, this is the file used to tell UTAU how to distinguish between the starting point of a sample, where the consonant begins, where the vowel is, the cut off of the sample, and how much of the sample is okay to stretch on longer notes.

Additional Terms to Know When Working With UTAU Software

UTAU: The name of the software, it is also the Japanese word for “Sing”.

Vocaloid: Perhaps the most well-known Vocal Synthesis program, developed originally for use by professionals. It is a commercial program that requires the user to purchase the base software as well as each additional voice they may want to use.

UTAUloid: An older community term used to refer to a specific UTAU character. Additionally, this term originates from “Vocaloid” and is in use alongside it.

Pitch: How high or low a tone is.

Timbre: The character or quality of a voice, different from pitch or intensity. Youthful, gruff, feminine, etc. could all be descriptors of timbre.

Vocal synthesis: The artificial production of human singing voices/voice-like instruments, much like speech synthesis. Common term when referring to UTAU, Vocaloid, and other similar applications.

Voicebank: A collection of voice samples and OTO(s) compiled for use within UTAU as a functioning singing voice. A Voicebank is usually alongside a character or mascot that represents the voice. Often referred to shortly as a “Bank”.

Vipperloid(s): A popular series of Japanese UTAU. You may recognize members such as Yokune Ruko and Sukone Tei. They originated from vip@2ch.

Nico Nico Douga/ニコニコ動画: Similar to a Japanese version of YouTube, this video-sharing website is incredibly popular with the Japanese Vocal Synth community.

Nikokara/ニコカラ: A Nico Nico Douga supported service that displays Hiragana song lyrics across a video.
