Sinsy (Singing Voice Synthesis System) (しぃんしぃ) is an online Hidden Markov model (HMM)-based singing voice synthesis system by the Nagoya Institute of Technology that was created under the Modified BSD license.
Overview The online demonstrator is free to use, but will only generate tracks up to 5 minutes. The user uploads data in the MusicXML format, which the Sinsy website reads to output a WAV file of the generated voice. Gender factor, vibrato intensity, and pitch shift can be adjusted prior to output.
As of December 25, 2015, the official developers of Sinsy were Keiichi Tokuda (Producer and designer), Keiichiro Oura (Design and Development), Kazuhiro Nakamura (Development and Main Maintainer), and Yoshihiko Nankaku.
It was originally available in Japanese and English, and Mandarin support was later added for the synthesis engine; however, the web interface still only supports Japanese and English.ITmedia ニュース - 初音ミクとも簡単に対話できる「MMDAgent」、その詳細を聞いてきた. Retrieved November 23, 2013
