the part of your recording where you don’t say anything at all). The offset is the part you want UTAU to cut off in the beginning of your voice file (a.k.a. Thus, it makes sense that your consonant value is generally in the middle of your voice file, where your vowel is the most consistent and stable. Which part of your recording UTAU stretches out is at the consonant value you set. The consonant is the reason why you don’t need to record voicebank sound files for a long time, since UTAU is able to stretch out the vowel.įor instance, if you want your UTAU to sing a “ra” note for three hours (not sure why, but if you wanted you could do it), you don’t need to actually record your ra.wav for three hours because UTAU can stretch out the “a” sound. In this case, when talking about oto.ini files, the consonant is the part where you want UTAU to stretch or loop for longer notes. Not to be confused with the same word when referring to vowels and the like. Generally, this is about half of the preutterance value. This is how much you want the vowel of the previous note to overlap with the consonant of the current note. This applies for all the other syllables except just vowels themselves. You know how when you say a syllable, there’s always a little bit of consonant before you say the actual vowel? Preutterance, then, is basically that division in between the consonant and the vowel (ie. In the UTAU oto.ini world, there are six important words/phrases you should probably know: There are many CV voicebanks that still sound amazing, so don’t worry too much about this for your first voicebank! However, this doesn’t mean CV voicebanks are bad. Because of this, VCV and CVVC voicebanks sound a lot more fluid and realistic (and generally not as choppy) as CV voicebanks sometimes do. However, the images below should give you a rough idea of the differences between CV, VCV, and CVVC voicebanks.Īs you can probably tell, VCV and CVVC have a lot more extra recordings you need to do. I won’t go too much into the details and differences between all of them, since this tutorial was meant mostly to give you a basic understanding of UTAU voicebanks. Since CV is the easiest to make, if you’re making an UTAU voicebank for the first time, many people recommend making a CV voicebank first. VCV and CVVC require you to record multiple syllables together in one sound file, and then take more oto-ing to create the finished voicebank.
Other types of voicebanks exist as well, the other popular ones currently being VCV (vowel-consonant-vowel) and CVVC (consonant-vowel-vowel-consonant).ĬV requires you to simply record each syllable separately, one time. * NOTE: Because of the consonant-vowel system, the voicebank you are currently making right now is called a “ CV voicebank.”ĬV voicebanks are the most popular and common because they’re the easiest to make.
“a,” “i,” “u,” “e,” “o,” and generally “n”) do not have consonants and only have vowels. Obviously, then, for syllables that are just vowels themselves (ie. The “k” part is the consonant and the “u” part is the vowel. Similarly, whenever you say “ku,” you can hear the “k” part before you actually hear the “u” vowel. The “sh” part is the consonant, and the “a” part is the vowel. The consonant part is basically the little part in every syllable that you say before saying the actual vowel.įor instance, when you say the syllable “sha,” you can hear the “sh” part before you actually hear the “a” vowel. Before we get into the specifics on voice configurations and the oto.ini, though, I’ll need to explain a few things first.Ī Little (But Important) Lesson on Audio and Linguistics (?)īefore we get to SetParam, there’s a few things about recordings that you should probably know.Įach syllable has two parts: a consonant and a vowel. However, if you want to create your own oto.ini file and really understand how UTAU works, then you’ll want to read this section carefully. If you want to do this, then there really is no reason for you to download or read this section about SetParam. That’s why often times, many people ask or pay others who are more knowledgeable to oto a voicebank for them. These voice configuration details are heavy, time-consuming stuff. (People sometimes use the word “oto” as a verb so if someone says they will “oto” a voicebank, that means that they will create an “oto.ini” file.) SetParam is a program that you will be using to create an “ oto.ini” file.Īn “oto.ini” file is basically just a file describing the voice configurations for each syllable you recorded.
