The model card we used is ResembleAI/chatterbox. Chatterbox Multilingual V3 keeps a 0.5B size and is described as improving speaker similarity and reducing hallucinations across languages. The card lists a long language set (Arabic, Danish, German, Greek, English, Spanish, Finnish, French, Hebrew, Hindi, Italian, Japanese, Korean, Malay, Dutch, Norwegian, Polish, Portuguese, Russian, Swedish, Swahili, Turkish, and Chinese) and calls the coverage 23 or more languages.
An English Chatterbox model on the same card is also 500M and exposes exaggeration control. Watermarked outputs are mentioned on the card.
