In their own words
NEUTRINO
NEUTRINO is an AI singing voice generator that synthesizes vocals from sheet music. Users provide lyrics and melody; the system estimates vocal timing, pitch, voice quality, and breathiness, then a vocoder produces the singing. The project says its models draw vocal traits from recordings made with performers' permission or audio released by public institutions, rather than existing pretrained models. The FAQ describes Muon voice retakes and adjustable quality and processing speed, with advanced, standard, and elements modes. Advanced and standard output is 48 kHz, 16-bit mono WAV; elements output is 24 kHz, 16-bit mono WAV. It is available for Linux, macOS, web, and Windows. Users download the software and add a voice library. NEUTRINO is free for general music and audio production, but embedding the software or using generated audio inside an application requires separate permission. Character-specific terms also apply to ordinary audio-file uses and vary by character and asset type. Users cannot currently create their own voice libraries with a released framework, according to the FAQ.
VoiSona Song
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.
