Convert your own singing, or a whole song, into one of six Japanese voices: AI Singer 御丹宮くるみ, AIみな〜ぎ, 夏目悠李, 小春音アミ, the JSUT-song singer and the official つくよみちゃん RVC model. Each carries its source credit and runs in your browser on NiceVois. Every conversion returns the normal RVC result and a Clean Consonants version.
NiceVoisボイスライブラリでは、声の持ち主または音声コーパスの権利担当者から利用許可を得た日本のAI歌声を、ブラウザだけで使えます。自分の歌声や曲をアップロードすると、選んだ声に変換され、通常のRVC出力と「Clean Consonants」版の両方を受け取れます。クレジットは各声の表示どおりに記載してください。

Convert with Tsukuyomi-chanHow it works
- Choose a voice. Each button above opens the converter with that voice already chosen.
- Add your singing, or a whole song. For a whole song, NiceVois separates the lead vocal first.
- Get two results: the normal RVC conversion, and a Clean Consonants version with more natural sibilance and breaths.
The first time you convert with a library voice, you agree to the Voice Library Terms. Each voice's own conditions are shown beside it before you convert.
A licensed voice licenses the voice, never the song. Hold the rights to the music you convert and publish, and credit the voice every time.
Common questions
Can I use these voices commercially?
Only where the voice says so. AIみな〜ぎ allows commercial use with credit. Koharune Ami permits commercial use with credit and Amitaro's all-ages terms. Treat results made with AI Singer 御丹宮くるみ, 夏目悠李, the JSUT-song singer and つくよみちゃん as personal and non-commercial unless you obtain separate permission.
Do I pay for a voice?
No. You never pay for a library voice. Converting with one works exactly like any other conversion on NiceVois: it counts as one of your free conversions, then your plan, and listening and downloads are free.
Can I download the voice model?
No. Library voices stay on NiceVois and are never downloadable. つくよみちゃん's official RVC model is also free to download from its official site if you want to run it yourself.
How do I credit a voice?
Every result made with a library voice shows the voice's exact credit and a Copy credit button. Use that credit wherever you publish.
Where do these voices come from?
Every voice here is used with documented permission from its creator or the corpus rights representative. NiceVois has no celebrity or look-alike voices.
