[Comment from Keiichiro Oura, Representative Director]

Listening to music, making it, and sharing it all happen on the smartphone in our hands today. And yet, enjoying singing voice synthesis has generally meant sitting down at a PC. We prepared a form that is complete on an iPhone or iPad alone because we wanted to set that assumption aside, just once. On the train to school, or lying in bed, you can have a melody you have just thought of sung back to you on the spot. With the same ease as humming to yourself, we want everyone to be able to work with a singing voice, regardless of country, gender, or age.

I would add that the voice libraries for "VoiSona" are built solely from data for which the rights have been properly cleared, such as recordings made with the permission of the rights holders. We do not use data gathered from the internet as training material without permission, nor do we use generative AI models whose training sources cannot be accounted for. An Android version is also in active development.

[About VoiSona]

"VoiSona" is a singing voice synthesis software that realistically reproduces human singing voices using the latest technology. The name "VoiSona" combines "Voice," meaning sound, and "Persona," meaning personality or charm, reflecting the goal of expressing diverse personalities through voice. The software supports both voice providers and creators, aiming to create a mutually beneficial ecosystem.

Based on the singing voice synthesis technology that Techno-Speech has built up over many years, the software is available on Windows, macOS, iOS, and iPadOS with VSTi/Audio Units support, making it easier to use and capable of meeting professional needs. It comes with a default Japanese voice library called "Chis-A" with a neutral tone. A simple standalone application is also included, so it can be used by those who do not have a DAW that supports VSTi/Audio Units. Audio waveform data output using "VoiSona" and "Chis-A" can, with some exceptions, generally be used free of charge by individuals and corporations alike, for both commercial and non-commercial purposes.
