Chatterbox TTS Pretrained Models

• General Use (TTS and Voice Agents):

  • The default settings (exaggeration=0.5, cfg_weight=0.5) work well for most prompts.
  • If the reference speaker has a fast speaking style, lowering cfg_weight to around 0.3 can improve pacing.

• Expressive or Dramatic Speech:

  • Try lower cfg_weight values (e.g. ~0.3) and increase exaggeration to around 0.7 or higher.
  • Higher exaggeration tends to speed up speech; reducing cfg_weight helps compensate with slower, more deliberate pacing.
