RealtimeSTT is a Python-based realtime speech-to-text engine emphasizing low latency, wake-word detection, voice activity detection, and automatic speech segmentation. It provides asynchronous callbacks, nanosecond-precision timestamps, and CLI tools, suitable for building voice assistants, meeting transcribers, or live caption systems.

Features

  • Real-time transcription via microphone
  • Wake-word and voice-activity detection
  • Asynchronous callback architecture
  • Nanosecond timing metadata
  • CLI and server modes with VAD filters
  • Low-latency suitable for live apps
