Speech to text for recordings, not live dictation

There are two ways to turn speech into text. Live dictation types as you talk. File transcription takes a recording you already have and returns the text afterwards. This page does the second one and cannot use your microphone.

If you want to type by voice right now, your device already does it. On Windows, press the Windows key and H. In Google Docs, open Tools and choose Voice typing. On a phone, tap the microphone key on the keyboard. If you would rather record first and read later, save the recording and upload it here.

Typing by voice and transcribing a file have different tips. The Voice to Text page sets out when to use which.

What you get back

The transcript appears on the page under a Transcript heading. The copy button puts it on your clipboard. The download button saves a .txt file named after your recording, with _transcript added.

It is plain text. There are no timestamps and no speaker labels, so a two-person interview comes back as one block of words. The page has no editor, so make your corrections in your own document.

Get your recording under 50 MB

The limit is on file size, not length. WAV files are the usual problem: a stereo WAV at CD quality reaches 50 MB at about five minutes. MP3 and M4A are compressed and fit much more speech in the same space.

Got a large WAV? Run it through the WAV to MP3 converter, then upload the MP3. Still too big? Split the recording and upload the parts one by one. If the speech is inside a video, use Video to Text instead.

Turn a meeting or interview into notes

  1. Upload the recording and convert it to text.
  2. Search the transcript for the names, dates, and numbers that matter, and check each one against the audio.
  3. Paste the text into your notes. Mark the decisions, action items, who owns each, and any quote you plan to use.
  4. Want only the short version? The Podcast Summarizer takes an audio file and returns a summary.

Get everyone's consent before you record a call, and do not upload a recording you are not allowed to share.

Check the transcript before you use it

  • Names and terms. Brand names, acronyms, and unusual spellings are the most likely errors.
  • Numbers and dates. Re-listen to any figure that goes into a report, an invoice, or a quote.
  • Overlapping voices. When two people talk at once, words get dropped or merged.
  • Muffled passages. Speech recorded far from the microphone, or over noise, is where the text gets vague.

For legal, medical, or compliance work, treat the transcript as a draft and use the process your organization requires.
