speech-to-text

Real-time transcription using faster-whisper

Accepts audio input from a microphone using a Sounddevice. By using Silero VAD(Voice Activity Detection), silent parts are detected and recognized as one voice data. This audio data is converted to text using Faster-Whisper.

The HTML-based GUI allows you to check the transcription results and make detailed settings for the faster-whisper.

Transcription speed

If the sentences are well separated, the transcription takes less than a second.
