"Retrieval-based Voice Conversion (RVC) is an open source voice conversion AI algorithm that enables realistic speech-to-speech transformations, accurately preserving the intonation and audio characteristics of the original speaker" (Wikipedia). This can be used within the context of UTAU to easily create new voicebanks, without needing to record new data.

NeoDIVA currently offers the following services relating to RVC, free of charge:

• RVC Model Training

• RVC to UTAU Conversion (Currently available in English Arpasing, JPN VCV and CVVC, and French CVVC.)

If you are interested in working with us for our RVC services please make sure that you read the T.O.S before hand, which can be found here.

If you have read through the T.O.S and agree to it you can register your interest with our submissions form, which can be found here.

If you are interested in volunteering your UTAU voicebank to be used as inference data for this service, please contact us directly either via email or through the NeoDIVA twitter account.
