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 first Vocaloids and Voiceroids went on sale on December 4, 2009. It differs from regular text-to-speech programs in that it gives users more control over settings like tempo, pitch, and intonation.
Overview
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. On October 22, 2010, a new version of the engine was introduced, known as Voiceroid+. The first voicebank released for this new engine featured a character from the children's anime Eagle Talon, known as Yoshida-kun. Much like Shouta and Ai, he is aimed at young audiences. The first three Voiceroids were subject to censorship, and inappropriate words were filtered out. However, Tsurumaki Maki was designed specifically for a more mature audience and is the first of the series to have no form of censorship. Yuzuki Yukari is also the first Vocaloid Vocaloid to have a Voiceroid voicebank. For Tohoku Zunko's release the software was vastly improved compared to previous Voiceroid+ voices. The first two Voiceroids to come in one package are Kotonoha Akane and Aoi. In 2015, the software was upgraded to Voiceroid+ EX. In 2017, the newest version of the software, "Voiceroid 2", was announced. This version has a number of new features and differences, though users can still import the past Voiceroid and its variants into it. However, older engine versions will not be able to use any new features. A number of releases for the software have been produced after successful crowdfunding campaigns; since 2016, this has become the main source of funding for new voicebanks.
