Voiceroid is a speech synthesizer application developed by AH Software and is designed for speech. It is only available in the Japanese language. Its name comes from the singing software Vocaloid, for which AH-Software also develops voicebanks. Both AH-Software's Vocaloids and Voiceroids went on sale on December 4, 2009.[1]

It differs from regular Text to Speech programs in that it gives the user more control over settings like tempo, pitch, and intonation.


Voiceroid uses an engine called AITalk developed by AI Inc. The user is able to adjust the tempo, pitch, and intonation to make the program sound more natural. The original two products Tsukuyomi Shouta and Tsukuyomi Ai were packaged with the animating software, Crazy Talk SE.[2]

On October 22, 2010, a new version of the engine was introduced known as, Voiceroid+. The first of this new engine featured a character from the children's anime Eagle Talon, known as Yoshida-kun. Much like Shouta & Ai, he is aimed at young audiences.

The first three Voiceroids were targeted at younger audiences, so they were subject to censorship, and inappropriate words were filtered out. However, Maki Tsurumaki was designed specifically for a more older audience and is the first of the series to have no form of censorship.[3]

Yuzuki Yukari is also the first Vocaloid to have a Voiceroid voicebank as well as a Vocaloid voicebank.

For Tohoku Zunko's release the software has been vastly improved compared to previous Voiceroid+ voices.

The first two Voiceroids to come in one package are Kotonoha Akane・Aoi.

In 2015, the software was upgraded to Voiceroid+ ex.[4]
