UTAU ([[IThoughtItMeant not to be confused]] with the ''Manga/ShugoChara'' character, or U'''at'''u, a Watcher from the MarvelUniverse) is a musical voice synthesis program created by Ameya as a freeware response to Music/{{Vocaloid}}. Using UTAU is much like using Vocaloid, however there are some differences in usage (which may lead to DamnYouMuscleMemory). Also, UTAU has the feature of importing vocal samples manually, which allows a person to use their own voice in UTAU.

Before the appearance of the now popular Teto Kasane, UTAU was virtually unknown. To date, there are over 1500 UTAU voicebanks from all over the world.

Near the end of 2009, Ameya created a special voicebank recording style first known as renzokuon, or "continuous sound", also widely called VCV (vowel-consonant-vowel). This allowed UTAU voicebanks to sound much smoother and more human than before. Another recording style a few years after that, referred to as CV-VC (consonant-vowel-vowel-consonant), quickly became popular due to allowing one to create voicebanks for different languages other than Japanese in the program. (Like, for example, english) A Mac version of UTAU, known as UTAU-Synth, has now been released, and a mobile version of the software is in the works.

[[folder: A detailed explanation of each recording style for those who care]]
* '''CV''':
** Often referred to as "Single Sound" in Japan, CV was the first recording style even created, and what the UTAU program was designed to work with. The Japanese language is made up of almost pure consonant-vowel clusters, with next to no ending consonants. (The closest thing resembling such being the 'm' and 'n' consonants, which can work like vowels in the program.) As such, this tends to be the most popular recording style as, not only because most Vocaloid songs are in Japanese, it's the easiest and quickest style to record in, possessing anywhere around 52 sounds.
** While it is the easiest to work with, it's not without it's problems. CV voicebanks tend to sound rather choppy due to the program artificially inducing vowel and consonant transitions, which results in it being viewed as the 'lazy recorder's method for those who don't want to spend the time making a VCV bank. While there may be ''some'' truth to this for some recorders, there is some unfairness in that accusation. CV voicebanks tend to be popular due to their ease of use on new comers, as well as the fact that they generally tend to take far less time to load when playing a song than VCV banks, as well as the fact that well put together CV banks can sound exceptionally smooth, to the point a few would swear that it was VCV bank if they didn't look into it. It all comes down to several factors on whether a CV bank was done out of laziness or a style choice, as there are a few who actually prefer the rather robotic tone CV can induce, saying it adds it's own bit of charm to the UTAU program.
*** A sub-type recording style of this, CV-VV, is essentially a CV bank with vowel-to-vowel transitions, to help make the CV bank sound smooth overall while still being lighter on the program than a VCV bank.
* '''VCV''':
** Known as "Continuous Sound" voicebanks in Japan, are voicebanks that are designed to have a more natural sounding vocal transition between phonetics. The recording style consists of recording vowels before each phonetic CV of a CV bank, allowing for the program to better transition from a previous vowel of the last phonetic, and to record natural vowel transitions for more natural sounding transitions in the program. The result often ends up sounding ''very'' smooth in the program, with some even verging on Music/{{Vocaloid}} quality. As a result, it tends to be the recording style most "professional" UTAU producers use, and what they feel ''every'' UTAU voicebank should be.
** As explained in the CV section, this is a bit of an unfair accusation. While VCV generally sounds smoother than CV, it is not without it's problems. Like with UTAU banks in general, the most well put together CV bank can out perform the laziest put together VCV bank by miles. In addition, VCV takes ''far'' longer to record, taking anywhere from around 200-300 samples in comparison to the 52 samples needed for CV. In addition, it leaves you with two choices to go for it's recording method. The first, and most popular one, is to record several phonetic samples and duplicate them using the inbuilt duplication program that comes with UTAU. This results in less file sizes over all, but takes ''far'' longer to load in the program than a CV voicebank. Also, because the recorder is chaining together several phonentics at once, the consonants can sound rather slurred when played in the program. The second, less popular method is to record each VCV separately, allowing for more control over the tone and sharpness of the bank. While this results in clearer vocals over all than the previous one, it also results in ''massive'' voicebank file sizes.
** In the end, it's up to the recorder to decide which they prefer. Extremely well put together VCV banks often times verge on Music/{{Vocaloid}} quality, while sometimes even out performing a few "official" Vocaloids, while lazily put together ones will often sound no different than lazily put together CV voicebanks.
*** It should be noted that this recording style can ''also'' be used to record voicebanks for different languages other than Japanese. However, regardless of what style you use for recording these kinds of VCV banks, the results will often barely sound better than CV-VC at most, in addition to being ''twice'' to ''three times'' as larger than a CV-VC bank. As a result, it's generally viewed that you better stick to CV-VC if you plan on recording voicebanks of other languages.
* '''CV-VC''':
** CV-VC voicebanks are one of the "newer" recording styles in the fact that they weren't created until several years after VCV was discovered. However, they quickly made their claim to fame in the fact that they allow one to make voicebanks for languages other than Japanese. The recording style focuses on CV with the addition of end consonants, which nearly every language outside of Japanese possesses. In order to record a VC, it's very much like a VCV where you record the vowel before the consonant, but stop upon saying the consonant, leaving a space of silence where the vowel in a CV or VCV bank would go so the program can naturally transition to the next phonetic without cutting off the end consonant. Upon it's discovery, CV-VC quickly exploded to one of the more popular recording styles due to allowing SurprisinglyGoodEnglish, as well as other SurprisinglyGoodForeignLanguage UTAU voicebanks, though some theorize it was created earlier before it's abilities for English banks were discovered.
** CV-VC is also a bit controversial as many claim that the results are "Better than Engloid", even though such accusations are flimsy at best. As with anything, general editing skill factors in heavily with both English UTAU and English Vocaloids. A well put together English UTAU can still sound like a drunken speak and spell in the hands of someone who has no clue what they're doing, while even the worst English Vocaloid can sound amazing in the hands of a professional. SturgeonsLaw also factors in heavily with this, as for the longest while English Vocaloids were ''far'' more accessible to the general public than their Japanese counterparts, in addition to the Japanese ones being more well know by professional Vocaloid users and fans, resulting in their better covers being posted to Website/YouTube. This resulted in mostly newbies to the program getting their hands on it, which contributed to a bit of a backlash against English Vocaloids. Rest assured, if one were to do a quick search on WebSite/NicoNicoDouga, one would find just as many SturgeonsLaw Miku, Kaito, and Len covers as there are Sonika, Big Al, and Leon covers on Website/YouTube. Thankfully, this kind of thought process seems to be slowly dying down thanks to a combination of SturgeonsLaw taking place with English UTAU voicebanks, as well as the English voicebanks that came out for most Japanese Vocaloids.
** That said, most agree that English UTAU on average have better control over the consonants and vowels thanks to the recording style, but such arguments can also be made for Japanese UTAU to Vocaloids. Another thing to note is that CV-[=VCs=], on average, take ''far'' more phonetic samples than CV or VCV Japanese. A single pitch CV-VC English bank can take anywhere between 300-''500''-to '''1000''' recording samples to get a natural sounding tone and smoothness to it. Naturally, this is because English is a far more complex language than Japanese, being one of the most complex languages in the world.
*** CV-VC is also not limited to English, either. Among many things, there are quite a few surprisingly good Spanish, Korean, and even French voicebanks floating around the net. This kind of style can also be applied to Japanese, but in a different way. Rather than end consonants being the end of the word, they more so serve as flag for where to start the next phonetic in editing, essentially meaning it serves as a way to artificially create VCV transitions without recording everything needed for a VCV bank. While the results of such generally sound just as smooth as VCV, it, like the other styles, is not without it's faults. If one were to listen closely, it ''is'' possible to hear the program playing the transition separately from the two [=CVs=], and can be a bit hard to unhear afterwards, and professional CV voicebanks on average can sound just as smooth. Still, for those who don't possess the editing skills for a professional CV or VCV bank, this presents a nice alternative.
* '''Multipitch''':
** Multipitch has been something that's been in the program for years, but was never really paid attention to until the creation of Ritsu's "Kire" voicebank. It can apply to any of the above recording styles if one wishes, and has a multitude of uses. The way to record it is to record your base samples, then record several more at different pitches and assign them to the appropriate tone range in UTAU, often by giving it a marker in the program.
** The uses for such a style vary. The original use was to allow for more natural sounding tone transitions, as well as taking less stress of the program itself so that it can plan each sample in a more natural sounding tone. However, the creator of Ritsu discovered that this application could be used for more dynamic tone transitions, allowing for a voicebank to have a more emotional tone to it than what a "monopitch" voicebank is capable of, and thus allowing for a wider range of music genres to use it for. Often times, most use it for rock songs and the like, but this technique can also be used for more mellow songs as well.
*** A common belief in the fandom is that having multipitch for the sake of multipitch is a bad thing, as the UTAU program is capable of replicating the tone of a non-dynamic monopitch voicebank rather perfectly. While there is some truth to this (in addition to multipitch banks being ''monsters'' when it comes to file sizes, especially for VCV and CV-VC) in that the program does manage to replicate the tone of your voice pretty well, it's not without ''some'' benefits. As said, multipitch takes a lot of strain off the program itself when it comes to replicating tones at higher pitches, which generally results in smoother sounding tones and far less mechanical rasp at higher pitches. It's really up to the user if they want to make a multipitch bank or not, because as said, many find that the possible mechanical rasp adds to an UTAU's charm.

Since all UTAU are essentially [[OriginalCharacter OCs]], opinions may be conflicting as to how fitting a trope may be. Edit with caution.

! Provides Examples Of:


[[folder: Tropes about the actual program, as well as general UTAU tropes.]]
* AllegedlyFreeGame: Or program. Regardless, if you want to make an UTAU that sounds even halfway decent, as well as make it sing well, hope you have a couple hundreds of dollars to spend on the necessary high quality microphone, vocal editing software, and possibly even music synthesizing software if you want to make music from scratch.
* AlternateCompanyEquivalent:
** The program itself, for starters, being the {{Freeware}} alternative to Music/{{Vocaloid}}.
** It's impossible to count the number of Music/{{Vocaloid}} [[{{Expy}} expies]] floating around in the fandom even with a dedicated list. Granted, this is often because of the fact that Vocaloids [[CrackIsCheaper can range anywhere between 200 to 400 dollars in price]] while UTAU voicebanks are, obviously, free.
* DamnYouMuscleMemory: Considering the interface is very similar to Vocaloid, with some minor to major differences, this is bound to happen. Of course, this trope works both ways if you used UTAU long before Vocaloid.
* DoItYourselfThemeTune: Naturally, considering making an UTAU based on the users voice is the first thing most people do upon getting the program. Depending on several things such as editing skill, microphone quality, and general voice tone, results can range from drunken karaoke to ''ear meltingly amazing''.
* ElectronicSpeechImpediment: Disregarding the fact that an UTAU's bank quality depends on a number of factors, sometimes a voicebank just flat out ''doesn't'' like one of the many resamplers out there, or the UTAU program ends up hiccuping for some reason. The end results of such can be rather... ''amusing'', to say the least.
* HeliumSpeech: Either done intentionally with some UTAU voicebanks for the lulz, unintentionally in an attempt to [[FollowTheLeader make UTAU Miku equivalents]], or as the result of putting the voicebank at an extremely high pitch.
* LoadsAndLoadsOfCharacters: ''Anyone'' can make an UTAU. Naturally, this means there are well over a thousand voicebanks and characters; however, only a handful of them have any popularity.
* {{Mascot}}: Surprisingly, no, it's ''not'' Teto Kasane, despite what the fandom insists. It's actually ''suppose'' to be Uta Utane, the voicebank that comes with the program created entirely from robotic speech synthesis. Doesn't stop people from seeing Teto as the unofficial mascot, though, thanks to her [[PopCultureOsmosis being the most well know UTAU outside of the fandom.]]
* LoadsAndLoadsOfLoading: Depending on how many phonetic samples are being used, the general speed of the resample being used, and if the phonetic samples only possess one sample (usually CV) or several (usually VCV), it can take a while for the UTAU program to load them all and play them out. Once it's loaded it though, it doesn't take nearly as long, but should you move a few things around...
* NotQuiteStarring: There are quite a few [[Music/{{UTAU}} UTAU]] voicebanks floating around the net based off of characters from either popular animes, video games, or even musicians, either through using [[{{Sampling}} voice samples from their show, game, or music]], or by someone [[TheOtherDarrin replicating their voice.]] It should be known though that, while (generally) there's no rule against creating these kinds of voicebanks, ''distributing'' said voicebanks on the net to the general public without the permission of whoever owns said character / music can get you in serious hot water with the show creator / game creator / musician, the creator of the UTAU program, and quite possibly a good portion of the UTAU fandom as well.
* OneSteveLimit: {{Zig Zagged}}. With the LoadsAndLoadsOfCharacters created on a daily basis, it's only natural that quite a few would share the same name. However, there seems to be an unspoken rule that naming characters after pre-existing Music/{{Vocaloid}}s or [=VIPPERloids=] is off limits. (And even then, there's some overlap thanks to some of the characters from those two coming out sharing a similar name with pre-existing UTAU.)
* RealityIsUnrealistic: Due to attempts to make UTAU sound either like anime characters, [[FollowTheLeader like Miku]], or generally make unique voice tones, this tends to pop up frequently with more 'realistic' voicebanks, often using the UTAU creators normal sounding voice. More often than not, you'll end up seeing at least ''one'' person complaining about a male UTAU not sounding like a chain smoker or a woman's voice being too deep to be a woman. [[labelnote: *]]Naturally, this is TruthInTelevision. Most men and woman tend to have similar vocal tones, with it usually being the rare exception that they diverge drastically like that, and usually not without some sort of outside interference. Not that this stop most people from complaining about it regardless.[[/labelnote]]
* RidiculouslyHumanRobot: Depending on how much effort is put into it, and how skilled the person using the voicebank is, some UTAU banks can sound surprisingly realistic, to the point you'd swear an actual human was singing it if you didn't know better. A good example is Ritsu's Kire voicebank, though it is by no means the only example.
* RoboSpeak: Depending on the skill level of whoever's using the voicebank, this is either PlayedStraight unintentionally or {{Averted}}. Keep in mind, the voicebank quality also depends on what mic is used to record it and how much editing is put into it. Some UTAU can sound like glorified speak and spells, while others can sound more realistic than Vocaloids, or even actual human singers!
* SmallNameBigEgo: There are quite a few UTAU creators who think their UTAU is the greatest thing since Teto Kasane, or even better than official Music/{{Vocaloid}}s, and are damn determined to make everyone aware of this fact. Whether such claims are actually true or not is [[RuleOfCautiousEditingJudgment a fact likely best left up to interpretation, and that's all we're saying about that.]]
* SturgeonsLaw: A given, considering it's the freeware equivalent of Vocaloid, and thus far more accessible to producers of varying skill levels. [[labelnote:*]]In addition to the fact many think only the UTAU program is needed to make great music when, in reality, it takes many different vocal editing programs just like Vocaloid to make it sound amazing, even with really well put together voicebanks.[[/labelnote]] Some songs and voicebanks can be exactly what you'd expect, but there are also quite a few that manage to put professional Vocaloid songs to shame, with some covers even out doing the original!
* SurprisinglyGoodForeignLanguage: While the program was originally made for Japanese vocals, it's not impossible to make voicebanks of other languages in it if you know what you're doing, as well as a good deal about the language in question's phonetic structure. Notably, in addition to Japanese, there are quite a few banks out there that support SurprisinglyGoodEnglish, as well as surprisingly Korean and good Spanish.
* VocalDissonance: Depending on the creator, this is either {{Invoked}} intentionally for the lulz with some UTAU, or a difference in opinions on the design matching the voice.

[[folder:General Character Tropes]]
* {{Anthropomorphic Food}}: Sekushii Beikon is a...piece of bacon.
* BigScrewedUpFamily: The Vippers, usually caused by either [[IdiotHero Teto Kasane]] or [[BigBad Sukone Tei.]] [[SubvertedTrope Doesn't mean they'll be the best of friends however.]]
* {{Bishonen}}: Ted Kasane, Taya Soune, Rook, and a good share of male [=UTAU=] fit this category.
* ComputerVoice: While this is technically true of all UTAU, Uta Utane stands out in that her voicebank was made 100% from a computer speech synthesis program, with no actual human voice actor providing the voice base. Depending on how she's used, she can range anywhere from MachineMonotone to having a surprising amount of emotion to her voice.
* CanonImmigrant: Teto, who started as an April's Fools Joke and became an [=UTAU=]. Also, the Macne Family, as well as Acme Iku, the Default family and Loline Com, weren't originally [=UTAU=]. Macne Family were [[CaptainObvious originally intended for Mac]], Acme Iku was originally from a hentai Flash app with a plethora of ero sounds, Defoko and her siblings were from [=AquesTalk=], and Loline Com had his own editor, which looked like a prototype of UTAU, even with similar mechanics.
* GenderBender: Some [=UTAU=] have two voicebanks, one male and one female. Also, around 70% of all UTAU voicebanks get a genderbent of some sort (sometimes, an older/younger counterpart of the same gender as well, which also uses the gender factor flag). The most famous are:
** Kasane Teto - Kasane Ted
** Sukone Tei - Sukone Teiru
** Nagone Mako - Nagone Makoto
** Suiga Sora - Suiga Sara
** Macne Nana - Macne Nanao/Macne Shichi (and sometimes, Macne Nana Petit as the younger counterpart)
** Acme Iku - Acme Ikuo
** Teira - Mashuu (and Tiramisu as the younger counterpart)
* HartmanHips: Exaggerated with Hana Chikako.
* RidiculouslyCuteCritter: [=InuHebi=].
* TrademarkFavoriteFood: Many [=UTAU=] have those. [[MeaningfulName Momo got peaches]], Teto got the French bread, Sora got the curry, Yufu got castella cake...
* {{Tsundere}}: Kasane Teto is regarded as a Type B. There are enough tsundere [=UTAU=] to make a list of its own.
* {{Troll}}: Some [=UTAU=] are made for this exact purpose; the most famous being the [=VIPPERloids=] Kasane Teto, Yokune Ruko and Namine Ritsu, who are April's Fools jokes from 2ch.
** Tei Sukone, also from 2ch, is another example. Her unoriginal design is a TakeThat at everyone whose [=UTAU bank's=] outfit is a PaletteSwap of Miku's, her personality is a TakeThat at fan characters who love Len and hate Miku, and her sharingan is a TakeThat to ''Manga/{{Naruto}}'' fan characters who have it. Unlike Teto and the other [=VIPPERloids=], however, she is immensely hated by the FanDumb who don't realize that she was MADE for trolling.
* SpotlightStealingSquad: Due to a combination of attempts to pass them off as "official" Vocaloids and [[LoadsAndLoadsOfCharacters the sheer amount of voicebanks created on a daily basis]], only the [=VIPPERloids=] tend to be relatively well know outside, and even inside, the UTAU fandom, with Teto being viewed as the unofficial mascot of the program.
* WholesomeCrossdresser: Ritsu is the most notable example of such, although there are quite a few crossdressing characters.
* {{Yandere}}: As with {{Tsundere}} [=UTAU=], there are many [=UTAU=] who fit this character type; [[{{Troll}} Tei Sukone]] and [[OurVampiresAreDifferent Amagaku]] are two popular examples.

[[folder:Original Song Tropes]]
* AmazonBrigade: [[https://www.youtube.com/watch?v=jNgCaDzrrUg Teto's "Confront, You Look So Cool!"]] has Teto putting together a team of [=UTAUs=], almost all of whom are girls. The only exception is [[TheOneGuy Sora Suiga]].
* AndIMustScream: The premise of ''[[http://www.youtube.com/watch?v=TCOow686QaI Time Glass]]'', as explained in the author's comments.
-->As some of you will remember from the original Grimm fairytale, the poison did not actually kill Snow White, it simply incapacitated her. In a way, she was in a coma for years until her prince found her. So, my concept was, what if she was conscious during that whole time, locked inside a glass coffin with no way to speak, or move, with only her thoughts as company. Thus this song was born.
* DomesticAbuse: Supposedly the theme to CIRCRUSH's [[https://m.youtube.com/watch?v=oURQnsw9yLE Biohazard]] by WordOfGod.
* DrivenToSuicide: One of the various interpretations given to [[http://www.youtube.com/watch?v=HY7ExbD5Hws Sky High]].
* HighClassCallGirl: "[[https://www.youtube.com/watch?v=NKYqJ3UvjIk Yoshiwara Lament]]" centers around one, and talks about her time dealing with customers and lamenting her lost love. If the PV is anything to go by, she'll get her happy ending.
* KidsAreCruel: In [[http://www.youtube.com/watch?v=orouoo9mYmo Daughter of an Evil Spirit]], kids made fun of Teto because she had wings on her back and red eyes. Although, adults joined on it.
* SenselessSacrifice: [[spoiler:Again, Daughter of an Evil Spirit.]] Although, it wasn't senseless on her part, but on those who sacrificed her. [[spoiler:The volcano still was active after she was sacrificed to it.]]
