How this service works
Transcribe an audio or video URL. Returns the transcript, ready-made WebVTT subtitles, and an editor's cut list marking every stretch of dead air and how much shorter the result would be. One flat price, $0.0200 per request, whatever the file. Sources up to 800 KB. A file that turns out to hold no clear speech is still billed — the transcription ran.
Output
Returns a full text transcript of the spoken content, a ready-to-use WebVTT subtitle file, and an editor's cut list that marks every stretch of dead air along with an estimate of how much shorter the final recording would be after those cuts. Files with no clear speech are still processed and billed.
Example use cases
Podcast dead-air cleanup
“I have a podcast episode at https://mypodcast.com/ep42.mp3 — can you transcribe it, get me the WebVTT subtitles, and show me the cut list of all the silent gaps so I know how much I can trim?”
Meeting recording to text
“We recorded our team standup at https://meetings.internal/standup_2024-06-10.mp4 — please transcribe it so I can share the text summary with the team.”
Video caption generation
“Can you generate WebVTT subtitles for the product demo video at https://cdn.example.com/demo_v2.mp4? I need them ready to embed on the website.”

Endpoint
POSThttps://transcribe.soboljem.cz/transcribeWhen to prefer
Choose this endpoint when you need a combined transcript, WebVTT subtitles, and an editing-focused dead-air cut list from a single audio or video URL in one flat-rate call. It is especially useful for podcast producers, video editors, and meeting-note workflows where identifying silences for trimming is as important as getting the spoken text.
Side effects

- URL is unreachable or returns an error — transcription fails
- Audio/video file contains no clear speech — still billed, transcript is empty or minimal
- Unsupported file format — transcription may fail
- Network timeout fetching the remote URL — processing error
