MP3 to Text Converter

• Accurate MP3 to text in dozens of languages

  Upload an MP3 and EchoWave's speech recognition turns it into a transcript in dozens of languages. Choose the spoken language and every word lands with its own timestamp against the waveform. Accents and technical vocabulary can trip any engine, so the whole transcript stays editable.

• Word-level timestamps

  Each word knows exactly when it was said. Click one to jump the playhead to that moment, which makes checking a quote against the original recording a two-second job instead of a scrubbing session.

• Fix mistakes in the browser

  Names, jargon and mumbled phrases are the usual weak spots for any transcription engine. Click into the transcript, retype the word, and the timing stays attached. No re-upload, no round trip through another app.

• Export TXT and JSON

  Grab plain text for notes, articles and show notes, or JSON with per-word timings if the transcript feeds your own scripts. Podcasters publishing episode pages can start from our podcast transcript generator.

• Turn the transcript into subtitles

  One click converts the transcript into subtitle cues you can export as SRT or VTT, or style with 176 caption presets, including word-by-word karaoke fills. If a subtitle file is the end goal, the SRT generator walks that exact path.

• Edit the audio by editing the text

  Delete a sentence in the transcript and the matching stretch of audio is cut from the timeline. Automatic filler removal strips the ums, uhs and long silences, useful when a rough voice to text note needs to become something publishable.

• Subtitle translation into 86 languages

  Once the transcript exists, translate the subtitle track into any of 86 languages, or show two languages at once with bilingual subtitles. Export the translated cues as SRT or VTT, or burn them into a video permanently.

• More than a converter

  The transcript lives inside a full multi-track editor, so the same MP3 can become a captioned clip, an audiogram with one of 93 visualizer styles, or a quote card. It runs in Chrome, Edge, Firefox and Safari with nothing to install.

1. 1

   Upload your MP3

   Drag the file into echowave.io from any modern browser on Mac, Windows, Linux or a Chromebook. WAV and M4A upload too, so voice memos straight off a phone need no conversion first.

2. 2

   Run speech to text

   Open the Subtitles panel, pick the spoken language, and generate. The engine transcribes the whole file and lines every word up against the waveform with word-level timestamps.

3. 3

   Review and correct

   Skim the transcript and click any word to hear that exact moment. Fix names and technical terms in place; edits keep their timing, so anything you export later stays in sync.

4. 4

   Export your text

   Save the transcript as TXT or JSON, or export subtitle files as SRT or VTT. You can also keep going in the editor and burn styled captions into a clip for social.

• Interviews

  Journalists and researchers get a quotable record with a timestamp on every word, so checking a quote against the tape takes seconds. Corrections happen inline without breaking the timing.

• Voice memos

  That idea you recorded on a walk becomes searchable text instead of a forgotten file. M4A memos from a phone upload directly alongside MP3s.

• Podcast episodes

  Publish a transcript with each episode for accessibility and search traffic, and pull show notes straight from the text. The same transcript drives captioned audiogram clips for promotion.

• Lectures and talks

  Students turn a recorded lecture into notes they can search before an exam. Slow playback to 0.25x for dense sections while following along in the transcript.

• Meetings and calls

  Upload a call recording and skim the transcript instead of re-listening to an hour of audio. Copy decisions and action items out as plain text.

• Oral history and archives

  Family recordings and archival tape become readable, searchable documents. Word timings preserve exactly where in the original each passage sits.
