What does audio to text mean?

Audio to text — also described as transcribe audio, MP3 to text or voice to text — means converting the speech in a sound file into written words. The audio file is not changed; you get a text version of what was said, usually with a time marker at the start of each line so you can find that part of the recording again.

People run audio to text on voice memos and voice notes, interviews, podcast episodes, recorded meetings and lectures, dictation, and any clip where reading is easier than listening. Unlike dictation built into an app, this works on a file you already have.

How to transcribe audio in 3 steps

  1. Have the audio file ready. MP3, WAV, M4A and OGG all work, including voice memos exported from your phone, up to 100 MB.
  2. Drop the file into the box above — or tap it to choose a recording on your phone.
  3. Press Transcribe. The text comes back with timestamps. Copy it, or download it as .txt or .srt.

What the transcript looks like

Every line starts with the moment it was spoken, so long recordings stay easy to scan:

[00:00] Quick note to myself about the client call
[00:06] they want the report by Friday morning
[00:12] and they asked for the numbers broken out by region

Download the text as .txt to paste into notes or documents, or as .srt when you need timed captions.

FAQ

Which audio formats can I transcribe?

MP3, WAV, M4A and OGG, and other formats your browser can decode. If it plays in the browser, the speech in it can be transcribed. Files up to 100 MB.

Is voice to text different from audio to text?

It is the same job described two ways: spoken voice in, written text out. A voice memo recorded on a phone is just an audio file, so it goes through the same box above.

Does the audio leave my device?

No. The model runs in your browser and the file is not uploaded anywhere. There is no account to create and nothing is stored on a server.

How long a recording can I transcribe?

Up to 100 MB per file. The audio is handled in 30-second passes, so an hour-long recording takes noticeably longer than a short memo and uses more memory in the browser.

Can I transcribe audio on my phone?

Yes. Open this page in a mobile browser and pick the recording from your phone. The first run downloads the speech model, so allow a little extra time on mobile data.

Which languages are supported?

English. The spoken language is identified first, and non-English audio returns a notice instead of a guess.
