RealtimeSTT is a Python library for low-latency, real-time speech-to-text with voice activity detection, wake word activation, and streaming transcription. It supports multiple ASR engines including faster-whisper, sherpa-onnx, and kroko-onnx for local speech recognition.
Use cases
- transcribe microphone audio in real time
- build a voice assistant with wake word activation
- add dictation to an app
- stream speech-to-text over websocket
- detect voice activity before transcribing
- run local speech recognition on CPU or GPU
When to choose
- you need low-latency realtime transcription in Python
- you want local, offline speech recognition with VAD and wake words
- you need streaming partial transcripts plus a final transcript
When to avoid
- you only need batch transcription of audio files with no latency requirements
- you need a hosted cloud ASR API rather than a local library
- your project is not Python-based
