## Latest Release: Chatterbox Multilingual V3

**Chatterbox Multilingual V3** is the latest general-purpose multilingual TTS model in the Chatterbox family. It keeps the same 0.5B model size while improving speaker similarity, reducing hallucinations, and producing more natural, conversational speech across languages.

Alongside V3, we are releasing the **Single Language Pack**: dedicated finetunes for priority languages where tighter quality control, stronger language-specific behavior, and more specialized speech generation are valuable.
