About Audio to Text

Audio to Text converts spoken audio into editable transcripts and timestamped subtitles. Speaker separation is optional: leave it off for a simpler transcript, or enable it when you need speaker labels and editable speaker names.

Common use cases

Transcribe interviews

Convert recorded speech from MP3, WAV or other supported audio into editable text.

Create subtitle drafts

Generate timestamped transcript output that can be used as a starting point for SRT or VTT captions.

Search spoken content

Turn a long recording into text so names, topics and quotes are easier to locate.

How it works

1

The browser decodes the selected audio into a format suitable for speech recognition.

2

A speech-to-text model analyzes the audio in chunks and predicts words with timing information.

3

The transcript is assembled into editable text and optional subtitle-style output.

Privacy & file handling

Speech recognition is designed for local processing

The supported transcription workflow processes the audio on the device rather than requiring the source recording to be uploaded to Zavilo.

Limitations and important notes

  • Accuracy decreases with background noise, overlapping speakers, strong accents, music or poor microphones.
  • Names, technical terms and numbers should be checked against the recording.
  • Automatic speaker separation, where available, can assign turns incorrectly and should be reviewed.
