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.[2]

As of December 25, 2015, the official developers of Sinsy were Keiichi Tokuda (Producer and designer), Keiichiro Oura (Design and Development),[3] Kazuhiro Nakamura (Development and Main Maintainer), and Yoshihiko Nankaku.[4]

It was originally only in Japanese and English, but Mandarin was later added; the website only supports English and Japanese despite this currently.[5][6]

In 2016, Sinsy stated using the deep learning processing technology DNN.[7]
