Developers and Researchers
Prototype voice features, test TTS pipelines, or experiment with voice cloning in an open-source model you can inspect and modify.
Game and App Developers
Generate placeholder or final character dialogue from a single voice sample. Iterate on voice direction without hiring voice actors for every draft.
Accessibility
Create personalized synthetic voices for people who have lost their ability to speak, using recordings from before their voice changed.
Getting the Most Out of Chatterbox
Tips for Best Results
Use clean reference audio
Background noise, music, or room echo will bleed into the cloned voice. Record in a quiet space or pick a clip with clear, isolated speech.
Stick to around 5 seconds
Longer clips do not improve quality. A focused 5-second sample of natural speech gives Chatterbox everything it needs.
One speaker only
If your reference clip has multiple people talking, Chatterbox may blend them together. Use a clip with a single, consistent voice.
Adjust exaggeration for the context
Use lower exaggeration (0.2 to 0.4) for calm narration or professional voiceovers. Use higher values (0.6 to 1.0) for animated character dialogue or expressive reads.
Use paralinguistic tags sparingly
Tags like [laughs] and [sighs] are most effective when used occasionally. Overusing them can make the output sound unnatural.

FAQ
Common Questions
Chatterbox Turbo is an open-source voice cloning model created by Resemble AI. It uses a zero-shot approach, meaning it can clone a voice from a single short audio sample without any training or fine-tuning. The model is designed for high-quality, expressive speech synthesis.
Chatterbox Turbo was developed by Resemble AI, a company focused on generative voice technology. They released it as an open-source model, which means anyone can use, inspect, and build on top of it.
Paralinguistic tags are special markers you can insert into your text to add non-verbal expressions to the generated speech. Chatterbox supports tags like [laughs], [sighs], and [gasps]. These make the output sound more natural and human compared to flat, monotone TTS.
About 5 seconds of clear audio works best. You can use clips up to 10 seconds, but longer samples do not necessarily improve quality. The most important factor is clean audio with minimal background noise.
The exaggeration parameter controls how expressive the generated speech sounds. A lower value produces more neutral, steady output. A higher value makes the voice more animated and emotionally varied. You can adjust it with a slider to find the right balance for your use case.
Yes. Chatterbox Turbo is open-source software released under the MIT license, one of the most permissive open-source licenses available. On this site, it runs directly in your browser with no account, no signup, and no usage limits.
The open-source Chatterbox Turbo model is primarily designed for English. For multilingual voice cloning, Voice Creator Pro includes Chatterbox Multilingual, an upgraded version that supports 20+ languages.
Chatterbox Turbo stands out for its zero-shot cloning quality from very short audio samples and its support for paralinguistic tags. Many other models require longer reference audio or lack expressiveness controls. Chatterbox Turbo focuses on English, but Chatterbox Multilingual, available in Voice Creator Pro, extends voice cloning to 20+ languages.
Chrome, Edge, and other Chromium-based browsers work best. Firefox and Safari have limited support for the WebGPU features that Chatterbox uses for acceleration.
