Main features of VoiSona

An AI singing program you can start for free

VoiSona is a singing program that reproduces how a person sings with AI, and its editor is released for free. Even before buying a voice library, you can have it actually sing and try the first 10 seconds of a song. The default voice library is Chis-A, a gender-neutral voice.

Works on computers and on iPhone and iPad

The PC edition works on Windows and macOS and can be used inside a DAW as a VSTi or AU plug-in. There are also iOS and iPadOS editions, which can be used standalone or as plug-ins (AU) in apps such as GarageBand, Logic Pro and Cubasis.

Voices for several languages

With the voices that support several languages, you can choose Japanese, English or Chinese and have them sing.

Adjust how it sings phoneme by phoneme

You can have it sing just by putting notes and lyrics on a piano roll, and you can also load MIDI and MusicXML files. You can shift the timing of each phoneme (vowel or consonant) of the lyrics forward or back, and draw by hand pitch, volume, vibrato, voice quality and huskiness while looking at the lines the AI produced. A style of singing that drops vowels, and falsetto, can also be reproduced by putting symbols in the lyrics.

Where it is useful

• Trying an AI singing voice with the free editor
• Having a voice sing in GarageBand on an iPad
• Making the vocal of an original song inside a DAW

Each criterion is scored from 1 to 5 on how well the product serves one goal: making a singing voice from a melody and lyrics. Scores follow the conditions in the table above. They are criteria chosen to match common searches about AI, singing in English, and whether it works on a Mac or a phone. The basis is official manufacturer information (official sites and manuals) and the Plugin Boutique product page. How natural the voice sounds has not been compared by ear, so it is not scored. Price and the number of voices are not part of the score. Features that cannot be confirmed from the manufacturer's or a retailer's description are scored as if absent.
