The audio sample and timed words come from the same MP3 submitted to the audio transcription service.
Speech, with start and end times.
What helps you start a new project?
I begin with one clear question,
then I listen to the people who will use it,
what do you do with their feedback?
I write down what they need,
test a small idea and improve it together.
This is one recorded service result; another run may divide the same speech differently. Words and times are uncorrected, and line breaks only improve display. Check the SRT before publishing.
Timed captions made from your audio.
Correct any spoken words, then download numbered captions with start and end times. The SRT is a separate text file, not a copy of your recording.
1Listen or watch while checking each caption against the source.
2Edit the words in the timed segments. The service-provided cue times stay the same.
3Download SRT and check its exact timing in the player or editor where you will use it.
Subtitles from a spoken recording.
Start with an MP3, M4A, WAV, MPEG, or OGG recording. The result is a downloadable SRT with the service’s timed speech segments.
A separate subtitle file
The SRT contains numbered text cues and timestamps. It does not contain the media or add captions permanently to a video.

Audio to SRT questions.
What audio files can I turn into SRT?
Upload an MP3, M4A, WAV, MPEG, or OGG recording with audible speech. This preview accepts files up to 100 MB.
Does the SRT file include my audio?
No. SRT is a separate text file with numbered captions and start and end times. Keep your original recording for playback or editing.
Can I correct the subtitles before downloading?
Yes. Edit the words in each timed segment or replace a repeated term. The edited text is included in your SRT download; cue times currently come from the transcription service.
Can I adjust individual cue times here?
Not in this preview. Listen to the recording and check the downloaded SRT in your video editor or subtitle player if exact timing is important.
Can I convert an existing subtitle file here?
No. This tool creates subtitles from spoken audio; it does not convert an existing subtitle file between formats.
Have a recording that needs timed captions?
Upload the recording, check its timed words, and download a separate SRT file.
