    Model Downloads

    Models are automatically downloaded from HuggingFace on first use:

    • Standard TTS: models/tts/chatterbox/resembleai_default_voice/
    • Multilingual TTS: models/tts/chatterbox/resembleai_multilingual/

    Tips for Best Results

    Language Transfer

    When using a reference audio in a different language than the target:

    • Set cfg_weight to 0 to mitigate accent transfer
    • Use a reference audio that matches the target language for best quality

    Japanese

    Japanese text is automatically converted to hiragana (kanji → hiragana, katakana preserved).

    Chinese

    Chinese characters are converted to Cangjie codes for tokenization.

    Korean

    Korean syllables are decomposed into Jamo for proper pronunciation.

    Optional Dependencies

    • resemble-perth: Audio watermarking support
    • dicta_onnx: Hebrew diacritization
    • russian_text_stresser: Russian stress marking
