[[caption-width-right:350:Luka, Rin, Len and Miku... [[LoadsAndLoadsOfCharacters we couldn't fit them all in if we tried.]][[note]]And, trust us, we ''have'' tried.[[/note]]]]

Vocaloids (from "vocal" and "android") are music synthesizing programs based on real human voice samples and technology created by the Yamaha Corporation. Think SyntheticVoiceActor meets AutoTune. There are currently 43 vocaloids (Rin and Len count as one product instead of two); and fans have created personalities for each character based on official art (some [[HeWhoMustNotBeSeen have no official art]]) and voice. Fans have also created characters based on official releases, such as Neru Akita and Haku Yowane.

To use a Vocaloid, one simply has to type in the lyrics of the song of his choosing as well as the melody for said song, although a great deal of fine-tuning is usually necessary to have the result sound natural. Vocaloids have become so popular that an official unofficial manga adaptation, ''HatsuneMix'', was created, telling the trials and tribulations of the Crypton-produced Vocaloid family: Meiko, Kaito, Miku Hatsune, Rin and Len Kagamine, and Luka Megurine.

''Vocaloid'' took major steps to becoming SeriousBusiness[[note]]On the Internet, anyway. Even with it extending into the real world, Vocaloid is still a niche thing, even to Japanese who identify as {{Otaku}}, with several of them not even knowing there are more Vocaloids than Miku Hatsune[[/note]]. Flagship character Miku Hatsune has become a fully-fledged VirtualCelebrity, with an album featuring her work (composed by synthesizer band ''Supercell'') nearly topping the Japanese music charts at No.2, and Miku herself putting on a ''live concert'' at Animelo Summer Live 2009. (Her "live" performances involve the same tech used for the {{Gorillaz}}' live shows and the [[TupacShakur 2Pac]] hologram from spring 2012.)

Toyota also began an ad campaign for their 2011-model Corolla, [[CharacterCelebrityEndorsement starring]] [[http://www.youtube.com/watch?v=E15PE7iGT0U Miku herself]]; it was subsequently revealed that Toyota sponsored Miku's first overseas appearance -- a live concert in Los Angeles at Anime Expo 2011.

In the 2010 Concert, Rin, Len, and Luka made debuts with [[http://www.youtube.com/watch?v=CS-mPtF7yDY&feature=related even better renderings]]. In addition, the Vocaloid song "Music/BlackRockShooter" (which features said character, created by artist huke) has inspired an official [[Anime/BlackRockShooter anime OVA of the same name]], which was produced by animation studio Ordet (ex members of KyotoAnimation) and was released on 2010. Another popular song, "Kokoro" seems to be getting its own ''[[http://rin-kokoro.com/ musical]]''. "Daughter of Evil", in turn, got its own theater play and later a manga. "Cantarella" got a musical, too. The song "Kagerou Days" and other songs related to it collectively dubbed "KagerouProject" also experienced a burst of popularity, enough to get a serialized manga and a novel written by the song's own producer, culminating in plans to produce an anime adaptation.

Miku had yet another overseas concert in Singapore during the [[http://www.animefestival.asia/hatsune_miku.html Anime Festival Asia 2011]] on November 11, 2011. In addition, during 2012's Miku Party concert, Kaito and Meiko made appearances. Starting May 6th, 2014 and going through June 3rd, Miku will be opening for LadyGaga [[http://www.animenewsnetwork.com/interest/2014-04-16/hatsune-miku-to-open-for-lady-gaga as a part of her [=ArtPop=] tour]], performing at no less than 16 different venues.

The producers {{Cosmo}}, {{Deco27}}, and {{mothy}} have their own pages, as does the band {{supercell}}, the music-video-making software MikuMikuDance and Creator/{{SEGA}}'s LicensedGame VideoGame/HatsuneMikuProjectDIVA.

'''Note: The following is only for tropes related to official Vocaloid material. For tropes on songs, fanon, and other fan works, go [[FanWorks/{{Vocaloid}} here]].'''

!!Provides examples of:
* AdaptationExpansion: The manga.
* AscendedFanboy: In a way. Popular Nico Nico Douga singer Piko now has his own Vocaloid, Utatane Piko, courtesy of Sony Music, besides being a professional singer himself.
* AmericanKirbyIsHardcore:
** The homepage for the [[http://notanotheranime.blogspot.com/2011/05/hatsune-miku-commercial-debut-toyota.html Miku Corolla advertising campaign]]. It seems like whoever drew her doesn't like certain ideas of cuteness... Toyota changed her appearance later, perhaps bowing to pressure from disappointed fans.
** Crypton's [[http://piapro.jp/static/?view=sf_japantown Piapro]] website held a contest for an official "American" Hatsune Miku design, and declared a [[http://exiled-artist.deviantart.com/gallery/#/d41incp winner]] (made by [[http://exiled-artist.deviantart.com Exiled Artist]]). WordOfGod indicates it will be used "in a commercial basis or in projects related to Miku's next concert". It was eventually used in the March 9, 2012 39's Giving Day concert when she performed ''[=PoPiPo=]''.
%% * AnimatedActors
* AnthropomorphicPersonification[=/=]MoeAnthropomorphism: One of the main reasons why Vocaloids are so popular.
* BreakoutCharacter: Miku Hatsune; she was only the seventh Vocaloid ever released, and yet she gained the most popularity among the fandom. These days, you can see a significant amount of fans who know more about Miku than any other Vocaloid, and sometimes learn about the franchise from her.
* TheCameo: Miku's first anime appearance was one of these in ''SayonaraZetsubouSensei'', as one of the people auditioning to be Meru's voice. Rin, Len, Kaito, and Meiko also appear in the same episode briefly, waiting in line for the auditions, however [[LawyerFriendlyCameo their coloring is off.]]
* CashCowFranchise: A huge hit in Japan and overseas, to the extent that there are musicals and even ''concerts'' of them!
* CatGirl:
** [=SeeU,=] the Korean Vocaloid from the V3 series, has cat ears on her headset.
** Iroha Nekomura. She has a HelloKitty design, with a big cat helmet and little cat-eared speakers, among other things. Her surname even means "Cat Village".
* ColorCodedCharacters: Many of the earlier Japanese Vocaloids had one dominant, unique color associated with them ([[color:red:Meiko]], [[color:blue:Kaito]], [[color:turquoise:Miku]], [[color:orange:Rin]]/[[color:yellow:Len]], [[color:pink:Luka]], [[color:purple:Gakupo]], [[color:green:Gumi]]); with the influx of new Vocaloids, this concept has largely been abandoned.
* ColorCodedStones: Aoki Lapis is named for the Lapis Lazuli Gemstone and has a color scheme of blue and purple.
* CoverVersion: [[ToMakeALongStoryShort If the song you're thinking of exists, they've probably covered it.]]
* {{Crossover}}: Thanks to HajimeKatoki, Miku is now also avalaible in [[VideoGame/VirtualOn Fei-Yen]] cosplay outfit, and Fei-Yen in a Miku Hatsune ShoutOut version.
* CurtainsMatchTheWindow: Several Vocaloids have this going on; namely Kaito, Miku, Sonika, Miki, Kiyoteru and Ryuto.
* TheCutie: [[http://www.youtube.com/watch?v=8SvhxTr96eo Aoki Lapis]], the V3 "Whisperloid."
* {{Defictionalization}}: Gakupo was based of voice samples from {{Gackt}}. Then Nico Nico held a vocaloid contest hosted by Gackt where they asked him to sing the winning songs ''Episode.0'' and ''Paranoid doll''. The result was Gackt not only created and released a remix of the song Episode.0. But he also created a video that was identical to the original Episode.0 pv but with the pictures of Gakupo replaced with pictures of ''Gackt'' dressed as ''Gakupo''. Here is the original pv of [[http://www.youtube.com/watch?v=2DQpbHzRlwo Episode 0]]. And here's the Gackt version featuring Gackt dressed as Gakupo [[http://www.youtube.com/watch?v=-SuBjr6hJb8 Episode 0 Gackt version]]
* DetachedSleeves: All of the V2 Cryptonloids have these, the same with most if not ''all'' their derivatives.
* DigitalPiracyIsEvil: MAIKA lists this as one reason why [[https://www.youtube.com/watch?v=z_oj_KzpRho she'll quit singing.]]
%% * FollowTheLeader: The [=UTAUloids=].
* GenreRoulette: They've toyed with damn near every genre of music known to man, the only genres they HAVEN'T toyed with would be [[DoomMetal Drone Metal, Stoner Metal,]] and FunkMetal.
* IdiotHair: IA, Miki, and Piko all have one. Piko's is especially notable in that [[http://images1.wikia.nocookie.net/__cb20110427080453/vocaloid/images/4/46/Illu_Vocaloid_Utatane_Piko-bust.png it's even shaped like a P]] to reflect his name.
%% * KaleidoscopeHair: Sonika.
* KatanasAreJustBetter: Gakupo Kamui. His katana is even said to be ''somehow related to his musical ability''.
* KayfabeMusic: At live concerts, the band is real enough, but the lead "singer" is a projected image (and not really a singer at all).
* MulticoloredHair: Galaco on her left side.
* LeftHandedMirror: Len and Rin Kagamine, opposite-gender mirrors of each other or HalfIdenticalTwins (depending on who you ask). This trope is most evident in Fanon works involving these two, as their official characterizations are virtually nonexistent.
* LoadsAndLoadsOfCharacters: There's quite a few already and the number is only growing. And that's not even getting into the fanmades and genderbends. Note that this number increases ''exponentially''. In 2010, the number of Japanese Vocaloids could be counted on both hands, and the number total were still easy to keep track of and to recite without issue. By the time 2012 arrived, the number had almost tripled.
* LoadsAndLoadsOfLoading: The PSP version of Project DIVA games are plagued with this, not surprising since most UMD-based PSP games have long loading times. Especially if you have the [=DLC=]s installed, as it needs to check the license everytime the list of DLC items are loaded.
* LyricalDissonance: Some of the nightmare fuel songs like "The path to eternal happiness I found it" can be misleading.
* MeaningfulName: Most official and fan characters. The 'Hatsu' of Hatsune (Miku's surname) means first; she was the first Japanese Vocaloid2 character and first of Crypton's "Character Vocal Series". The 'Kagami' part of Kagamine (Rin and Len's surname) means 'mirror'; Crypton once described them as mirror images instead of being twins, although they [[FlipFlopOfGod backtracked]] on that. The 'Meguri' of Megurine (Luka's surname) means circulating/revolving; a reference to her bilingual capabilities. Furthermore, the 'ne' at the end of Kagamine, Hatsune, and Megurine means 'sound'. Akita Neru means 'I'm tired; going to sleep' and Haku Yowane means 'weak-willed words'. In fact, the name "Akita Neru" was coined ''because'' of the troll who created her using the phrase ''akita, neru'' ('I give up; going to sleep'), as a reaction of frustration about the difficulty of using the VOCALOID software.
** Lily's voicebank was sampled from the singer Yuri Masuda. "Yuri" means "lily" in Japanese and similarly, Gakupo, voiced by Gackt (pronounced Gakuto) and Gumi, voiced by Me''gumi'' Nakajima. Utatane Piko, voiced by Nico singer [[ExactlyWhatItSaysOnTheTin Piko]].
* NoExportForYou: Many of the non-English Vocaloids are rather difficult to get if you don't live in Japan, and shipping can get to ridiculous prices. Yamaha attempted to avert this with some [=Vocaloid3=] banks such as [=VY1V3=], Mew, Aoki Lapis, Tone Rion, and the [=V3=] Gumi banks available as downloads, Voctro-Labs ships Bruno and Clara internationally, and SBS put up [=SeeU=] on [=eBay=] (albeit at a considerably higher price), but some, like Yuzuki Yukari, are still rather difficult to get overseas.
** In addition: Do you want to buy an album by your favorite composer, or a compilation album? Unless it's registered on [=KarenT=], you will probably never be able to get it, because they're usually sold at Comiket or [=VocaMas=] - and even if they're sold online too, they're usually on Japanese-only sites.
** Even if you can read Japanese (or use a translator for your browser) good luck seeing any of the Theatrical Plays based on the more famous songs. Those few that do have DVD releases never seem to have subtitles, English or otherwise.
** And then there's the licensed games, notably the VideoGame/HatsuneMikuProjectDiva series, which were Japan exclusives until Project Diva f, which at least was made available in the Southeast Asia region, but that's it so far (and it's still in Japanese). There are hopes however for the latter to see international release, seeing as how an ''American'' promotional video for the PSVita shown in Gamestops shows gameplay footage of that game.
** Averted with Project Diva F for the {{PlayStation 3}}. After Sega posted on their Official {{Facebook}} [[https://www.facebook.com/photo.php?fbid=10151538674841796&set=a.133608051795.134727.28248536795&type=1&relevant_count=1 page]] the possibility of a western release of Project Diva F for the PS3 if they get enough likes and shares (a stunt similar to what Crypton did for Miku's English voicebank), they eventually met their target and subsequently announced the release of the localized version of the game in the US and Europe, eventually released on August 27, 2013.
** But the special mention goes to the another Miku x SEGA game, ''Project mirai'' for the 3DS (It's Nintendo's ''Project Diva'' with ''Nendoroid''-ified Vocaloid! [[Main/RuleOfCute Kawaii!]]). The game's never released outside Japan, both prequel and sequel. Meaning you'll never play them if you don't own a Japanese 3DS. And yes, the fans are begging for their lives for the localization.
** Actually, Yamaha updated en.vocaloidstore.com (where they sell Vocaloids), and they now sell packaged versions of [=SeeU=], Tone Rion, MEW, Aoki Lapis, and other Vocaloids to North America and Europe!
* OneMarioLimit: A visual variant. Any other character with big twintails of a similar color will be confused with Miku.
%% * OnlySixFaces
* OppositesThemeNaming: Rin and Len Kagamine. Their names are a pun on the words "right" and "left", respectively.
* RapunzelHair: Miku, and to a lesser extent Luka, Galaco, Nekomura Iroha, Mew, Haku and Neru. Fanartists tend to draw it ''even longer'', to the point of it being longer than the character is tall.
** With the addition of Vocaloid3 IA and her very long hair, which is comparable to Miku, it goes down to her ankles.
* RecursiveAdaptation: Gakupo was based of {{Gackt}} who then made a remix of a Gakupo song and PV.
* RidiculouslyHumanRobots: So human, in fact, that you'll soon forget that they're robots.
** Especially the V2 Appends and most of the Vocaloid-3's.
** Except in the cases of Piko and Miki; both have robotic joints and the former has what appears to be an equalizer ''as part of his left eye.'' Oh, not to mention the tail-like [=USB=] cable.
* SiblingYinYang: Between Len and Rin.
** This is somewhat emphasized in the Append artwork; Rin's outfit is mainly light with some darker elements, while Len's is mainly dark with some lighter elements. And the [[http://weekly.ascii.jp/elem/000/000/029/29482/1_cs1e1_x584.jpg boxart.]]
%% * SuperDeformed: Hachune Miku
* VideoGame/SuperRobotWars: Miku Hatsune as the [[VideoGame/VirtualOn Virtuaroid Fei Yen]] in VideoGame/SuperRobotWarsUX.
* [[TalkingToHimself Talking To Herself]]: Rin and Len are voiced by the same person.
* ThemeTwinNaming: Rin and Len are puns on "R" (right) and "L" (left).
* {{Vaporware}}: We haven't heard much of [=CV04=] and its existence since its confirmation in 2009, and details get more and more scant as time passes by.
** WordOfGod says that he's still in production. However, he might not be in the ''Character Vocal'' series anymore since he's now listed as "Male Vocal" rather than "[=CV04=]".
** Also Suzune Ring and Hibiki Lui have pretty much been abandoned.
%% * VirtualCelebrity: Miku provides the page picture.
* TheVoiceless: In Project Diva F, DLC characters Yowane Haku, Akita Neru, and Kasane Teto are not given voices when in the interactive mode. They do sing, however, which is odd. Curiously enough, Haku and Neru, who were adopted as "official" characters by Crypton, do not actually have official voices, which leads to Miku and Rin users downpitching the vocals to give them some semblance of a vocal identity.
* WolverinePublicity: Miku is something of an internet sensation, and a lot of people would like her to feature in their own properties, not just as a virtual voice actor but as herself-- even a minimal role will do, as long as they get to display her prominently in their advertising. An example of this would be ''Videogame/SeventhDragon'' 2020, where she appears as Hatsune Miku Type-2020.
* YouGottaHaveBlueHair: Kaito, Gakupo, Miku, Luka, Gumi, Sonika, Miki, Iroha and Gachapoid's [[MoeAnthropomorphism human form]].
* ZettaiRyouiki: Hatsune Miku and, subsequently, many other female (and sometimes male) Vocaloids.
