How to Use Chatterbox TTS
Follow these simple steps to transform your text into high-quality AI speech with Chatterbox TTS.
Input Your Text
Simply enter the text you want to convert into speech in the Chatterbox TTS interface. Chatterbox TTS supports detailed prompts, allowing you to specify desired tones, emotions, or contexts. The more precise your input, the better Chatterbox TTS aligns with your expectations. For optimal results with Chatterbox TTS, include details like desired emotion or pacing to guide the speech generation process.
Customize Voice Settings
Adjust emotional intensity, pitch, or voice style using Chatterbox TTS's customizable settings. Chatterbox TTS offers extensive options to fine-tune the generated speech, from neutral narration to highly expressive dialogue. You can also upload a reference audio for zero-shot voice cloning, enabling Chatterbox TTS to replicate a specific voice accurately. These settings ensure the audio produced by Chatterbox TTS perfectly fits your project requirements, whether for podcasts, games, or virtual assistants.
Voice Control Tips:
Exaggeration
Controls the expressiveness of the voice. Neutral = 0.5. Extreme values can lead to instability.
Higher exaggeration (e.g., 0.7 or higher) tends to speed up speech.
CFG Weight (or Pace)
Controls the speed and rhythm of the voice, often used in conjunction with exaggeration.
If the reference speaker has a fast speaking style, lowering CFG Weight to around 0.3 can improve pacing. For expressive or dramatic speech, try lower CFG Weight values (e.g., ~0.3).
Random Seed
Controls the randomness of the voice generation process. Set to 0 for complete randomness.
By setting a fixed random seed, you can repeatedly generate similar voice outputs.
Temperature
Influences the randomness and variability of the generated voice.
Generate & Download
Click the generate button to instantly let Chatterbox TTS process your text into high-quality audio.
