UTAU ([[IThoughtItMeant not to be confused]] with the ''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 {{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. As of recent years, another new recording style, CV-VC (consonant-vowel-vowel-consonant) has became rather popular due to allowing one to create voicebanks for different languages other than Japanese. (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.

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: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 [=UTAUloids=] fit this category.
* CanonImmigrant: Teto, who started as an April's Fools Joke and became an [=UTAUloid=]. Also, the Macne Family, as well as Acme Iku, the Default family and Loline Com, weren't originally [=UTAUloids=]. 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 [=UTAUloids=] 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.
* InstantAwesomeJustAddNinja: Nagone Mako is the most notable example of this trope.
* 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.
* RidiculouslyCuteCritter: [=InuHebi=].
* TrademarkFavoriteFood: Many [=UTAUloids=] 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 [=UTAUloids=] to make a list of its own.
* {{Troll}}: Some [=UTAUloids=] are made for this exact purpose; the most famous being the [=VIPPaloids=] 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 [=UTAUloid'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 {{Naruto}} fan characters who have it. Unlike Teto and the other [=VIPPaloids=], however, she is immensely hated by the FanDumb who don't realize that she was MADE for trolling.
* WholesomeCrossdresser: Ritsu is the most notable example of such, although there are quite a few crossdressing characters.
* {{Yandere}}: As with {{Tsundere}} [=UTAUloids=], there are many [=UTAUloids=] who fit this character type; [[{{Troll}} Tei Sukone]] and [[OurVampiresAreDifferent Amagaku]] are two popular examples.

[[folder:Original Song Tropes]]
* 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.
* DrivenToSuicide: One of the various interpretations given to [[http://www.youtube.com/watch?v=HY7ExbD5Hws Sky High]].
* 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.]]
