How this service works

Takes an audio or video file by URL or inline base64 and reports who spoke when. Every turn comes back with its speaker label, start and end time, duration, word count and text, and consecutive words from the same speaker are merged into one turn rather than left as a word list.

Output

A list of merged speaker turns, each containing a speaker label (e.g. SPEAKER_00, SPEAKER_01), start time, end time, duration in seconds, word count, and the full text of that turn. Consecutive words from the same speaker are merged into a single turn rather than returned as individual words.

Example use cases

Meeting recording speaker breakdown

“I've got a Zoom call recording at https://example.com/team-standup.mp4 — can you split it up by who's speaking and tell me what each person said with timestamps?”

Interview transcript attribution

“Here's an audio file of a journalist interview: https://example.com/interview.mp3. Can you identify the different speakers and show me exactly when each one talked, with the text of what they said?”

Legal deposition speaker segmentation

“I need to label the speakers in this deposition audio — it's at https://example.com/deposition.wav. Please return each speaker's turns with start time, end time, and the words they said.”

When to prefer

Choose this endpoint when you need per-speaker segmentation of audio or video — not just a raw transcript. It is ideal for meeting recordings, interviews, podcasts, depositions, or any multi-speaker audio where knowing who said what and when is the primary goal. Prefer this over a plain transcription endpoint when speaker attribution and turn boundaries matter.

Side effects

Unsupported audio/video format returns an error
File URL unreachable or access-denied results in a fetch error
Very long files may time out or exceed processing limits
Base64 payload too large may be rejected
Single-speaker audio may return only one label with no meaningful diarization
Overlapping speech may cause incorrect speaker boundaries
