Chatterbox Multilingual: Latin American Spanish

Chatterbox Multilingual: Latin American Spanish is a dedicated single-language finetune in the Chatterbox Multilingual V3 Single Language Pack. It is optimized for Spanish as spoken in Latin America and Mexico, with language- and region-specific behavior for expressive text-to-speech and voice cloning.

Use this model when you want tighter Latin American Spanish quality control than the broad multilingual checkpoint. For a single model that covers all supported languages, use ResembleAI/chatterbox.
