Choose the SDK for your target device.
Integrate the on-device STT library.
Feed live audio and receive transcripts in real time.
Live captions, commands, or dictation go live.
Recognition happens locally — no audio leaves the device.
Real-time transcripts as speech happens.
Neural models tuned for accuracy and speed.
Integrates across mobile, desktop, and embedded.
Built for responsive, live transcription features.
Commercial-friendly open-source terms.
Download the source and move into the project folder.
git clone https://github.com/Picovoice/cheetah.git
cd cheetahEvery project documents its own setup; start with install requirements.
cat README.md | head -60Follow the project's launch command — Docker, pip, npm, or a binary release.
