Chatterbox | Speech to Speech

Chatterbox Speech to Speech is an open-source AI that turns spoken input into natural, clear speech. It supports multilingual synthesis, zero-shot voice cloning from a few seconds of audio, and fine control over emotion and delivery. Creators can tailor tone, pace, and expressiveness while preserving speaker identity. Built-in watermarking enables responsible use and traceability. Benchmarks show strong intelligibility and listener preference versus leading commercial tools. Ideal for voiceovers, assistants, podcasts, games, accessibility, and real-time translation. For best results, use 5–10 seconds of clean reference audio and adjust emotion gradually. Higher quality settings improve realism but may require stronger GPUs.
