We're excited to introduce Chatterbox, [Resemble AI's](https://resemble.ai) first production-grade open source TTS model. Licensed under MIT, Chatterbox has been benchmarked against leading closed-source systems like ElevenLabs, and is consistently preferred in side-by-side evaluations.
|
|
|
|
Whether you're working on memes, videos, games, or AI agents, Chatterbox brings your content to life. It's also the first open source TTS model to support **emotion exaggeration control**, a powerful feature that makes your voices stand out. Try it now on our [Hugging Face Gradio app.](https://huggingface.co/spaces/ResembleAI/Chatterbox)
|
|
|
|
If you like the model but need to scale or tune it for higher accuracy, check out our competitively priced TTS service (<a href="https://resemble.ai">link</a>). It delivers reliable performance with ultra-low latency of sub 200ms—ideal for production use in agents, applications, or interactive media.

# Key Details
|
|
- SoTA zeroshot TTS
|
|
- 0.5B Llama backbone
|
|
- Unique exaggeration/intensity control
|
|
- Ultra-stable with alignment-informed inference
|
|
- Trained on 0.5M hours of cleaned data
|
|
- Watermarked outputs
|
|
- Easy voice conversion script
|
|
- [Outperforms ElevenLabs](https://podonos.com/resembleai/chatterbox)
|
|
|

# Tips
|
|
- **General Use (TTS and Voice Agents):**
|
|
- The default settings (`exaggeration=0.5`, `cfg=0.5`) work well for most prompts.
|
|
- If the reference speaker has a fast speaking style, lowering `cfg` to around `0.3` can improve pacing.
|
|
|
|
- **Expressive or Dramatic Speech:**
|
|
- Try lower `cfg` values (e.g. `~0.3`) and increase `exaggeration` to around `0.7` or higher.
|
|
- Higher `exaggeration` tends to speed up speech; reducing `cfg` helps compensate with slower, more deliberate pacing.

# Installation
|
|
```
|
|
pip install chatterbox-tts
|
|
```
|
|
|
|
|
|
# Usage
|
|
```python
|
|
import torchaudio as ta
|
|
from chatterbox.tts import ChatterboxTTS
|
|
|
|
model = ChatterboxTTS.from_pretrained(device="cuda")
|
|
|
|
text = "Ezreal and Jinx teamed up with Ahri, Yasuo, and Teemo to take down the enemy's Nexus in an epic late-game pentakill."
|
|
wav = model.generate(text)
|
|
ta.save("test-1.wav", wav, model.sr)
|
|
|
|
# If you want to synthesize with a different voice, specify the audio prompt
|
|
AUDIO_PROMPT_PATH="YOUR_FILE.wav"
|
|
wav = model.generate(text, audio_prompt_path=AUDIO_PROMPT_PATH)
|
|
ta.save("test-2.wav", wav, model.sr)
|
|
```
|
|

# Built-in PerTh Watermarking for Responsible AI
|
|
|
|
Every audio file generated by Chatterbox includes [Resemble AI's Perth (Perceptual Threshold) Watermarker](https://github.com/resemble-ai/perth) - imperceptible neural watermarks that survive MP3 compression, audio editing, and common manipulations while maintaining nearly 100% detection accuracy.
