1. Tutorial Introduction

Chatterbox is an open source text-to-speech (TTS) model released by Resemble AI on May 28, 2025, designed to provide high-performance, flexible speech synthesis solutions. This model is the first open source TTS model that supports emotional exaggeration control. It is based on the LLaMA architecture with 500 million parameters and is trained with more than 500,000 hours of selected audio data. It supports multi-language and multi-timbre generation, and its performance exceeds that of closed-source systems such as ElevenLabs.

One of Chatterbox's core features is zero-sample voice cloning, which can generate highly realistic personalized voices with only 5 seconds of reference audio without the need for a complex training process. In addition, it supports emotional exaggeration control, allowing users to adjust the emotional intensity, speaking speed, and intonation of the voice to make the voice more expressive. Chatterbox's ultra-low latency real-time synthesis capability, with a latency as low as less than 200 milliseconds, makes it suitable for interactive applications such as virtual assistants and real-time dubbing. To ensure the security and traceability of content, Resemble AI's Perth neural watermarking technology is embedded in the audio generated by Chatterbox to prevent abuse.

The main innovations are as follows:

Emotional exaggeration control: By adjusting the parameters (such as exaggeration = 0.7 + cfg = 0.3), you can achieve a speech style from bland to dramatic.
Real-time synthesis capability: inference delay < 200 ms, suitable for real-time interactive scenarios

The computing resources of this tutorial use a single RTX 4090 card. The prompt words of this model only support English.

2. Operation steps

1. Start the container

If "Bad Gateway" is displayed, it means the model is initializing. Since the model is large, please wait about 2-3 minutes and refresh the page.

2. Usage steps

When using the Safari browser, the audio may not be played directly and needs to be downloaded before playing.

1. Text Generation

Specific parameters:

Text to synthesize: Enter the text to be converted into speech. The maximum length is 300 characters (text that is too long will be automatically truncated).
Reference Audio File (Optional): Provides a reference audio file to allow the system to mimic the speaker's voice style, intonation, and rhythm.
Exaggeration (Neutral = 0.5): Controls the exaggeration of emotional expression and voice tone.
CFG/Pace: Controls the rhythm and speed of speech.
Random seed (0 for random): Set the random seed.
Temperature: Controls the randomness and diversity of speech expressions.
