Sinsy vs VoiSona Song

Sinsy is a free web service that generates singing vocals from musical scores. You upload a MusicXML score, choose a vocal, and adjust settings labeled ALP, VIB, and PIT; Japanese appears as a language option. The system uses DNN- and HMM-based synthesis to model characteristics such as pitch and timbre, rather than accepting vocal input. Sinsy was developed by the Tokuda, Nankaku, and Hashimoto Laboratory. Its version history lists version 5.1 on 2026/05/01, with fixes for parameter-panel and smartphone/tablet behavior. Earlier entries record compressed MusicXML upload support in version 4.4 on 2023/12/25 and the addition of Japanese DNN vocal f01027j_dnn_beta5 in version 4.5 on 2024/12/25. The service is listed for web and Linux. Its Free online synthesis plan costs nothing. The synthesis page says using the service implies agreement to its terms of use. The about page is available in Japanese and describes the research background and version history.

VoiSona Song is AI voice synthesis software that reproduces human singing. It is available on iOS, macOS, and Windows, with a free editor and the Chis-A voice library available at no cost. Users can create vocals by entering notes and lyrics in a piano roll, importing MIDI into a DAW, or uploading MusicXML files. Editing controls cover phoneme timing, pitch, volume, vibrato, voice quality, and huskiness. On PC, the app can run on its own or as a VSTi or Audio Units plug-in. The iOS/iPadOS app runs standalone or as an AUv3 plug-in compatible with GarageBand, Logic Pro, Cubasis, and more. Export formats include WAV, MIDI, MusicXML, CCS, CCST, tsmsln, tssprj, and Lab; commercial use is allowed. Before a voice library is purchased, the free editor can make voices sing only the first 10 seconds of a song. Paid song voice libraries offer monthly, annual, and outright purchase options, with prices varying by library and displayed in yen. Sign-up is required, and an internet connection is needed for installation and some features. CeVIO Creative Studio and CeVIO AI exclusive voice libraries cannot currently be used.
