Transcribe voice recordings, dictations, and audio notes into written text using Web Speech recognition.
Live Microphone to Text Dictation
Uses your device microphone in real time — browsers cannot transcribe an uploaded audio file this way
This tool transcribes what your microphone hears live — it does not read or process an uploaded audio file. Speak into your microphone after pressing "Start Live Dictation".
