# Pocket TTS\n\n\n\nA lightweight text-to-speech (TTS) application designed to run efficiently on CPUs.\nForget about the hassle of using GPUs and web APIs serving TTS models. With Kyutai's Pocket TTS, generating audio is just a pip install and a function call away.\n\nSupports Python 3.10, 3.11, 3.12, 3.13 and 3.14. Requires PyTorch 2.5+. Does not require the gpu version of PyTorch.\n\n[🔊 Demo](https://kyutai.org/pocket-tts) | \n[🐱‍💻GitHub Repository](https://github.com/kyutai-labs/pocket-tts) | \n[🤗 Hugging Face Model Card](https://huggingface.co/kyutai/pocket-tts) | \n[⚙️ Tech report](https://kyutai.org/blog/2026-01-13-pocket-tts) |\n[📄 Paper](https://arxiv.org/abs/2509.06926) | \n[📚 Documentation](https://kyutai-labs.github.io/pocket-tts/)\n\n\n## Main takeaways\n* Runs on CPU\n* Small model size, 100M parameters\n* Audio streaming\n* Low latency, ~200ms to get the first audio chunk\n* Faster than real-time, ~6x real-time on a CPU of MacBook Air M4\n* Uses only 2 CPU cores\n* Python API and CLI\n* Voice cloning\n* Multi-language support: english, french, german, portuguese, italian, spanish\n* Can handle infinitely long text inputs\n* [Can run on client-side in the browser](#in-browser-implementations)\n\nAdditional languages may be added in the future.\n\n## Trying it from the website, without installing anything\n\nNavigate to the [Kyutai website](https://kyutai.org/pocket-tts) to try it out directly in your browser. You can input text, select different voices, and generate speech without any installation.\n\n## Trying it with the CLI\n\n### The `generate` command\nYou can use pocket-tts directly from the command line. We recommend using\n`uv` as it installs any dependencies on the fly in an isolated environment (uv installation instructions [here](https://docs.astral.sh/uv/getting-started/installation/#standalone-installer)).\nYou can also use `pip install pocket-tts` to install it manually.\n\nThis will generate a wav file `./tts_output.wav` saying the
