Transcribe the audio track of an MP4 video

MP4 is a media container often used for video recordings, including phone clips, recorded talks, and exported interviews. This MP4 to text tool transcribes the audio track of a video into text you can copy or download.

Choose an MP4 with recorded speech and an audio track your browser can decode. The tool uses the browser's audio decoder. If decoding fails, try a different browser or convert the recording to WAV/MP3 before trying again.
