•required 50 / 300

Text for speech synthesis, limited to 300 characters and supporting 23 languages. Available languages include English and French; German, Spanish, Italian, and Portuguese; Hindi and Arabic; Chinese, Japanese, and Korean, among others.

Advanced voice · custom_audio_language · exaggeration · temperature · cfg_scale · seed
default english

Synthesis language code, with custom use requiring both an audio URL and a selection for custom_audio_language.

Language setting that applies only when the voice is supplied as a custom URL; otherwise it is ignored. Specify the language spoken in that custom audio.

default 0.5

Speech expression and emotional intensity relative to the neutral setting of 0.5. Increasing the value adds expressiveness within the 0.25–2.0 range, though extreme settings may cause instability.

default 0.8

Adjust speech-pattern variety by setting generation randomness between 0.05 and 2.0; increasing the value produces more variation.

default 0.5

Generation guidance weight for configuration/pace. For language transfer, 0.0 helps limit accent inheritance; the full range is 0.0–1.0.

Generation seed with two behaviors: 0 selects random generation, whereas a specific number makes outputs reproducible.

About Chatterbox · Text to Speech · Multilingual

Synthesizes speech in many languages, including English, French, German, Spanish, Hindi, Arabic, Chinese, Japanese and Korean. Text is limited to 300 characters. `voice` sets the language, or a custom audio URL together with `custom_audio_language`. `exaggeration` ranges 0.25 to 2, and `cfg_scale` can be set to 0 for language transfer to reduce accent carryover.
