Audio to SRT: give spoken words their place in time.
Audio to SRT turns speech into a subtitle file that tells a player which words to display and when. Start with an MP3, M4A or WAV recording, review the generated captions, and download a subtitle file for your next editing step. This audio to SRT guide covers cue structure, timing and the checks that matter before publishing.
Choose the audio that matches your project.
Audio to SRT accepts MP3, M4A and WAV recordings and defaults to subtitle output. A WAV export from an editing project, an M4A voice memo and an MP3 podcast can all be starting points. Choose the recording whose timing matches the media you will publish; the captions follow the file you upload.
If your source is specifically an MP3 episode or an extracted MP3 soundtrack, the MP3 to SRT workflow covers those cases in more detail. M4A and WAV users can start directly in the audio to SRT uploader above. For a document without subtitle timing, choose Audio to Text and its TXT export.
Audio to SRT supports recordings up to 2 GB and five hours, within your account’s remaining minutes. These limits do not increase the free allowance. Video uploads and meeting links are not supported here: export a supported audio file from your own source media before starting.
What does audio to SRT put in a subtitle file?
The audio to SRT result uses SubRip Subtitle, a plain text format. Each block is called a cue. It contains a sequence number, a start time, an end time and the words shown during that interval. A blank line separates one cue from the next. The following is an illustrative example, not a transcript of your recording.

without listening to the whole
conversation again.The first cue begins eighteen seconds into the uploaded audio and ends at twenty-one seconds and four hundred milliseconds. The timestamp uses hours, minutes, seconds and milliseconds, with a comma before the milliseconds. Those times describe positions in the recording, not the time of day when someone spoke.
Audio to SRT produces timing and text, not a copy of the audio or video. Keep your original media and import the subtitle file alongside it. The final player or editor controls how the captions appear; the file alone is not a finished, captioned video.
Create and check your audio to SRT result.
Start audio to SRT by selecting a recording and checking its duration against your available minutes. Leave language detection on automatic, or select English when appropriate. When you start the task, ScribeText transcribes the speech and prepares timed caption segments. You do not need to bring a written script or manually type the entire recording first.
When audio to SRT completes, open the subtitle view and listen through the captions. Correct the words before making fine timing adjustments: adding a missing phrase or removing an incorrect word changes how much a viewer needs to read. Save your edits so the downloaded SRT reflects the checked version.
Check audio to SRT timing wherever a cue appears early, disappears too quickly or stays visible through a long silence. Leave a pause empty when nobody is speaking instead of stretching a sentence across it. Download the SRT when you are ready, then play it with your actual publishing media. That final check catches differences between the audio you uploaded and the sequence you eventually export.
Make subtitles comfortable to read.
Audio to SRT needs a reading pass as well as a spelling check. A long sentence shown briefly asks viewers to read faster than they can follow the picture. Break lines at natural phrase boundaries where possible, and avoid separating a person’s first and last name or leaving a tiny word on its own line.
The audio to SRT subtitle view flags timing and reading issues such as unusually short or fast cues. Treat those indicators as prompts to review the audio, rather than instructions to stretch every subtitle mechanically. A cue should remain connected to the speech it represents and should not cover the next speaker’s words.
For an interview, check interruptions and quick exchanges especially carefully. For a lecture, give terminology a second look. For a narrated clip, watch the final video as well as listening: a caption can be readable on its own while obscuring important text already visible in the frame.
Take the subtitle file into your editor.
Adobe Premiere
For an audio to SRT result destined for Premiere, import the SRT as media and place it in the matching sequence as a caption track. Import the file, place it against the matching audio and review the alignment. Adobe’s caption import instructions describe the steps. Styling and final video export happen in Premiere.
YouTube
YouTube accepts the basic UTF-8 subtitle format used by audio to SRT. Upload the captions for the matching video and check their timing in preview. YouTube’s supported subtitle formats explain its restrictions, including that SRT styling markup is not recognized. Do not rely on an SRT file to preserve a branded font or custom layout.
Other subtitle workflows
Before importing into another editor, confirm that its current version accepts SRT. Some workflows require a different format or treat caption positioning differently. Preserve your reviewed audio to SRT export as a reference. After conversion in another application, check a cue containing punctuation or an accented name as well as its timing.
Troubleshoot audio to SRT timing.
Audio to SRT timestamps start at the beginning of the uploaded recording. If the final video adds an introduction before that audio, the whole subtitle track may need a matching offset. If you cut a sentence from the middle, captions after that edit may need separate adjustment. A single offset cannot repair every sequence change.
Check the beginning, middle and end of the finished piece. When the difference grows over time, investigate whether the audio was sped up, slowed down or replaced with a different version. Do not keep shifting only the first cue while leaving the rest of the track progressively misaligned.
Run audio to SRT on the final audio edit whenever possible. If you must change the edit afterward, use your subtitle or video editor to align the affected cues. Keep a note of the source file so you can distinguish a timing mismatch from a transcription mistake.
When audio to SRT is the right output.
| Your goal | What you need |
|---|---|
| Read or reuse a conversation | A TXT transcript, without a subtitle schedule. |
| Import timed captions | An SRT file plus the matching audio or video. |
| Publish text permanently on the picture | A video editor that renders captions into the final video. |
Audio to SRT exports a separate file; it does not burn captions into a video. It also does not translate the speech or automatically create every non-speech caption a publication might need. Review speaker identification and meaningful sound descriptions in your final captioning workflow when they are necessary for viewers to understand the scene.
Audio to SRT questions.
Can audio to SRT work without an existing transcript?
Yes. Audio to SRT recognizes spoken words and associates them with times in the recording. If you only have a plain text script and no recording, it cannot establish when those words were actually spoken. A text file alone is not a substitute for the supported audio input.
Are the captions ready to publish automatically?
Review the audio to SRT result first. Noise, accents, unfamiliar names and overlapping speech affect the words; pauses and rapid exchanges affect timing. Check the SRT against the final media, particularly after cuts or changes in playback speed.
Can I try it before choosing a plan?
You can try audio to SRT by signing up with Google or your email address. Verified accounts receive ten free minutes once. Pro provides 800 minutes each month for $8 monthly or $60 billed yearly, with no rollover. New source audio is kept for 30 days, so retain your own media copy for later subtitle adjustments.
