Vosk

Alpha Cephei

Vosk is an open-source offline speech-recognition toolkit designed for mobile devices, desktops, servers, and embedded hardware. It provides streaming transcription, speaker identification,...

Pros

  • Runs offline on relatively modest hardware, like Picovoice
  • Supports streaming recognition and many common developer languages
  • Permissive Apache 2.0 licensing is suitable for commercial projects

Cons

  • Recognition accuracy and language breadth generally trail leading cloud APIs
  • Tooling is less polished and comprehensive than Picovoice's commercial SDK suite
  • Does not provide an equally broad set of wake-word, intent, and voice modules

Free and open source
