VoxCPM is an open-source audio project by OpenBMB (OpenBMB/VoxCPM on GitHub). It has 38,415 GitHub stars and 4,343 forks, is released under the Apache-2.0 license, and was last updated on GitHub on 8 October 2026.
Decide what you want from VoxCPM and check the README and requirements to confirm it fits your setup and Python environment.
Clone the repository from GitHub (github.com/OpenBMB/VoxCPM) or use the documented install channel if you do not need the source.
Follow the README quickstart to install dependencies and set any required configuration or credentials.
Work through the README's first example end to end, then adapt it to your own project or data.
A tokenizer-free architecture for text-to-speech from OpenBMB.
Generates speech across many languages.
Create new voices creatively from descriptions, per the project highlights.
True-to-life voice cloning from reference audio.
Documents production deployment via Nano-vLLM and vLLM-Omni, plus on-device llama.cpp-omni inference.
Usable through a Python API, a CLI and a web demo.
Start by getting the source and entering the project directory.
git clone https://github.com/OpenBMB/VoxCPM.git
cd VoxCPMInstall the Python package from PyPI.
pip install voxcpmUse the Python API or CLI to synthesize your first utterance or clone a voice.
voxcpm # see README for the exact command — CLI UsageIt is maintained by OpenBMB and contributors on GitHub, where the repository github.com/OpenBMB/VoxCPM is the canonical home for code, issues and releases.
Yes — it is open source under the Apache-2.0 license. Read the license in the repository for what is permitted, including any conditions on redistribution or commercial use.
No. VoxCPM runs locally or on your own serving stack; no API key is required.
Compared with Coqui TTS: VoxCPM is a modern tokenizer-free model with voice design and cloning built in, versus Coqui's toolkit of classic architectures.
Clone github.com/OpenBMB/VoxCPM, follow the README quickstart to install it, and run the documented first example before adapting it to your own work.
