About this tool
Resemble AI’s speech-to-speech feature turned a person’s recorded or live speech into a different synthetic voice while keeping the timing and expression of the original performance. It was available through the company’s web application and API. A product notice on Resemble AI’s site now says the product is no longer available, because the company has stopped offering voice generation as a paid product.
In an article explaining the decision, its co-founder writes that existing voice customers are still supported but new ones are not being accepted. The voice models the team built, including Chatterbox and DramaBox, remain open and free to build on under a research programme, but no new voice models are planned for sale. The company has put its whole effort into identifying synthetic media.
Resemble AI now sells detection and provenance tools: an API that judges whether audio, video or images are synthetic, a watermarking service compatible with C2PA, identity matching against an enrolled voice or face, and fraud pattern matching. These products serve contact centres, meeting platforms, trust and safety teams and investigators rather than creators looking for voice conversion.
