**UTAU:** Japanese word for “Sing” and name of the Program. UTAU is a Freeware Vocal Synthesis program in the same vain as VOCALOID.

**VOCALOID:** A commercial Vocal Synthesis program, more popular than UTAU. There’s a lot of crossover between VOCALOID Music and UTAU, as UTAUloids often cover VOCALOID songs.

**Vocal synthesis**: What UTAU and VOCALOID does; the act of creating a musical instrument from a real voice. By taking samples of a real voice and programming them a certain way, we can “make a computer program sing.”

**Voicebank:** The folder of .WAV or .aaif files containing the recordings of the UTAUloid. Usually paired with an avatar/character of some kind. Often shortened to just “Bank.”

**.WAV:** The file format recognized within the UTAU program and used for Recording an UTAUloid. UTAU won’t read a voicebank full of .mp3 files.

**UTAUloid:** A term derived from “VOCALOID” (Which itself is a contraction of the words “Vocal + Android”) It is used to refer both to the voicebank and the avatar/character associated with the voicebank. Many UTAU users treat the voicebanks they’ve created like OCs.
Ex. “This is my UTAUloid, I voiced her myself!”

**Vipperloid(s):** A series of popular Japanese UTAU originating from vip@2ch.

**.UST:** Utau Sequence Text Files. The file format that the UTAU program uses. Similar in style to sheet music or a MIDI file.

**MIDI:** (Musical Instrument Digital Interface) A file format often used in the creation of UST files.

**Flags:** Voice modifiers written into the properties of a UST. Can make a voice sound sweeter, softer, more muffled or more breathy etc depending on which flags are used.

**OTO.ini:** The configuration file for making a voicebank sing correctly.

**Alias:** Alternate names given to the WAV recordings in the OTO.ini file. Multiple aliases can be given to a single WAV recording. Used heavily with VCV voicebanks.

**CV:** “Consonant Vowel” Style voicebank. The smallest and simplest style of voicebank. (see: [[CV]])

**Rentan:** A style of CV voicebank where sets of CV samples are recorded all at once, instead of split up into individual files. Works identically to a standard CV voicebank within the program once configured.

**VCV:** “Vowel Consonant Vowel” Style voicebank. The most popular form of voicebank. While much larger/takes more recordings to create compared to a CV bank, it’s much smoother as a result. (see: [[VCV]])

**Mora:** The amount of syllables in a recording string. This word is particularly used in relation to reclists.

**Lite VCV:** A shorter/smaller version of a VCV voicebank with most of the same smoothness as a full VCV bank. Recommended to those who find VCV lists too daunting to record.

**CVVC:** A CV voicebank with added “VC”s. At it’s best, nearly indistinguishable from VCV with more flexibility, at it’s worst a little better than a CV bank with a strange tone to it. (see: [[CVVC]])

**VCCV:** A newer style of voicebank used primarily for English language UTAUloids developed by Cz. (see: [[VCCV]])

**Multipitch:** A voicebank where multiple single banks are put together to allow for a much greater range.

**Kire:** A popular recording style of Multipitch voicebank where the tone of the voice gets stronger in the higher pitches, as opposed to keeping a more consistent tone throughout.

**Prefix map:** The file that dictates which pitches of the Multipitch voicebank sing on which notes. Can be changed by the user freely.

**Appends:** voicebanks recorded with a particular tone in mind, such as “Soft” “Dark” “Strong”. Another term derived from VOCALOID. Can be a standalone bank, or within a Multipitch bank.
**
Tuning:** The practice of manually changing the pitchbends of a note to make the voicebank singing the song sing in a more pleasing way.

**Consonant Velocity:** A tool that changes the speed at which the Consonants of samples are played. Useful for when a bank is singing very fast or making a bank “slur” their singing.

**Resampler:** The engine used to read the WAV files in the voicebank folder to then be played in.

**FRQ:** The resampler doesn’t read/change the pitch of the WAV files in the folder directly, so FRQs are what the resampler makes and then uses to play a voicebank’s files in the UTAU program.

**Mixing:** The process of taking the Vocals you’ve rendered in the UTAU program and blending it with the off vocal/karaoke of the song.

**Fl Studio:** A DAW (Digital Audio Workstation) often used to mix songs.

**Reaper:** Another DAW that is often used to mix songs.

**Nico Nico Douga (ニコニコ動画):** A popular video sharing website in Japan, sort of like an anime-centric Japanese Youtube. UTAU and VOCALOID covers and originals are frequently uploaded here.

**bilibili (哔哩哔哩):** A popular video sharing website in Chinaーessentially being a Chinese version of Nico Nico Douga. UTAU and VOCALOID covers/originals are frequently uploaded here.

**Nikokara (ニコカラ):** A form of video uploaded Nico Nico Douga where the lyrics of songs are displayed across the video screen, written in Hiragana/Furigana. Useful for making UST files.

**Audacity:** A DAW often used to record voicebanks and to mix songs.

**OREMO:** Another Free software used for recording. Created specifically for recording voicebanks. (see: [[OREMO]])

**setParam:** A voicebank configuration program outside of UTAU. Popular for generating/editing OTO.ini files. Comes alongside Oremo. (see: [[setParam]])
