Dub that sounds like acting
The performance survives the translation.
Most dubs sound like someone reading the subtitles. The Spanish take keeps the same pause and half-laugh as the English original, because the performance transfers, not just the words.

200+ languages with Realtime TTS-2 and Realtime TTS-2 Flash, with one voice identity preserved across every language. See Realtime TTS-2 launch intel for the full list.
Instant cloning with 5-15 seconds of reference audio. Professional cloning with 30+ minutes for higher fidelity. Cross-lingual cloning preserves voice identity across every supported language, clone in English, dub in Spanish, French, German with the same voice.
Yes. Professional Voice Clones (PVC) are available for studio-scale workflows with licensing coordination, dedicated training, and higher-fidelity models. Contact sales for PVC scoping.
Cloning requires rights to the source audio, and rights clearance sits with you. The tooling and infrastructure are ours; the licensing is yours. Cloned voices belong to your account under the Inworld terms of service and can be used commercially within that scope.
Dubbing is typically asynchronous (non-streaming TTS endpoint). The Realtime API is not the dubbing path, it's the live avatar path. For live speech-to-speech translation use cases, the Realtime API plus a translation-layer LLM gives you near-realtime dubbed response.
Realtime TTS-2 adds natural-language voice direction, conversational awareness (the model hears prior-turn audio, not just transcripts), crosslingual identity preservation across 200+ languages, and Advanced Voice Design with three stability modes. That's where 'dub that sounds like acting' comes from — performance-level output rather than translated reading. Realtime TTS-2 is available now in research preview; contact sales for production access.
