MP3 to text

Convert MP3 to text

Upload an MP3 and get it back as a document: punctuated, with a timestamp on every line, ready to copy, edit or download.

The short answerTo convert an MP3 to text, upload it to SpeakToWords and wait a few minutes. The file is transcribed by a current speech model and comes back punctuated and timestamped; download it as TXT or DOCX for documents, or SRT and VTT for subtitles.

How it works

  1. Upload the MP3Any bitrate works; 128 kbps or higher gives the best results. Up to 500 MB.
  2. Wait a few minutesA one-hour MP3 is usually done in under six.
  3. DownloadTXT and DOCX for reading and editing; SRT and VTT for subtitles.

Does the bitrate matter?

Less than people think. A 64 kbps spoken-word MP3 transcribes almost as well as a lossless file; what costs accuracy is noise, music and distance from the microphone, not compression. Do not convert to WAV first - it only makes the upload bigger.

Long files

A single MP3 can be up to 2 hours on Basic and 10 hours on Pro, so a whole conference day or audiobook chapter does not need splitting.

Questions

Is it free?

A free account transcribes 15 minutes with no card and shows the opening of each transcript; the full text unlocks with the 7-day trial or a plan from €9.99 a month for 500 minutes (€4.00 for 3 months until 6 December).

How accurate is it?

On clear speech, upwards of 99% of words come back right, punctuated and with a timestamp on every line. Background music, people talking over each other, strong accents and unusual names cost accuracy; the editor plays the audio from any line so you can fix those quickly.

Does it label who is speaking?

Not yet. Every line carries the second it was said, so you can jump to it and listen, and add names in the editor. If speaker labels are essential, see the comparison pages for tools that offer them.

What happens to my file?

It is processed for you only, encrypted in transit, and never used to train anything.
