Speaker Diarization
Make multi-person recordings usable by separating speech into speaker-labeled segments. Designed for meetings, interviews, panels, and podcasts, diarization improves clarity and reduces time spent manually identifying who said what. An editable timeline supports fast corrections, and the resulting structure improves downstream tasks like dubbing, captioning, and accurate summaries.
Key Features
- Reliable speaker separation: Groups speech by speaker for clear “who said what” transcripts.
- Editable speaker timeline: Merge/split speaker segments for fast correction when needed.
- Built for real conversations: Handles interruptions and rapid back-and-forth more effectively than basic tools.
- Unlocks better dubbing/captions: Improves multi-speaker dubbing and subtitle accuracy by clarifying speaker turns.

How it will work
- 1
Add your multi-speaker recording
Bring a meeting, interview, panel, or podcast file. The tool is built for real conversations with interruptions and rapid back-and-forth.
- 2
Speakers get separated and labeled
Speech is grouped by speaker into a clear "who said what" transcript, with each turn placed on a timeline you can review.
- 3
Correct and export the result
Merge or split segments on the editable timeline to fix any mix-ups, then export a structure that also improves downstream dubbing and captions.
Frequently asked questions
- What audio formats does speaker diarization support?
- MP3, WAV, M4A, AAC, OGG, and FLAC — the formats meeting, interview, and podcast recordings usually arrive in.
- How many speakers can it tell apart?
- The tool is designed for real multi-person conversations—meetings, interviews, panels, and podcasts—rather than just two people, and it aims to handle interruptions and rapid back-and-forth.
- Can I fix it when a speaker is labeled wrong?
- Yes. Rename any speaker, move a turn to a different speaker, or split a turn onto a new one when two people were merged — and your corrections are saved with the transcript.
- Is diarization the same as transcription?
- Not quite. Transcription turns speech into text; diarization figures out who spoke when and labels each turn. Together they produce a clear, speaker-attributed transcript.
- Can I export the transcript?
- Yes — download it as TXT, SRT, or VTT, so the same speaker-labeled result works for documents, subtitles, and captions.
