How to Transcribe a Voice Memo to Text (MP3, M4A, WAV)

The Voice Memos app records; it does not read back. A voice memo to text converter gives you the words with the time they were said, which is the difference between an idea you had in the car and an idea you can find. Here is how, for files you already have and for recordings you make in NoteBase.

  1. If you already have the file

    Share the memo from your phone as a file - iPhone memos are M4A, most Android recorders produce MP3 or WAV - and drop it into the upload box on the Multilingual Voice Recorder page. Choose the language the transcript should be in; it does not have to be the language spoken.

  2. If you are recording now

    Press Record on the same page or in the app. The recorder keeps going with the screen off and stops where your weekly allowance does, keeping what you said. Recording in NoteBase skips the export step and the note is ready when you press Done.

  3. What comes back

    A transcript in full sentences, split by speaker where more than one voice is present, with an interactive timestamp on every paragraph; and above it a summary of what was said. A 10-minute memo is usually back in well under a minute.

    • Speaker tags separate every voice in the room
    • Timestamps jump the player to that second
    • 100+ languages, and bilingual recordings in one pass
  4. Two settings that change the result

    The output language, and whether the note is a plain transcript or a summary template - a meeting template will hand back decisions and action items rather than a narrative. Both are chosen before you upload, and both can be re-run on the same recording.

Questions about this guide

Which formats are supported?

MP3, M4A and WAV, plus the audio track of common video files. Voice memos shared from an iPhone arrive as M4A and need no conversion.

Is there a length limit?

Long recordings are split into chunks and transcribed in parallel, so a two-hour recording works; it takes a few minutes rather than a few seconds.
