Automatically identify and label different speakers

Multi-person recordings are the norm in professional settings, meetings, interviews, depositions, focus groups, and panel discussions all involve multiple speakers whose contributions must be accurately attributed. Without speaker identification, a transcript is just a wall of text with no way to know who said what. Blazescribe's speaker diarization technology solves this by analyzing voice characteristics and conversation patterns to identify each participant and maintain consistent labeling throughout the recording. The technology handles the real-world challenges of multi-person audio: speakers with similar voices, crosstalk, long pauses, and varying audio quality. Teams using speaker identification report that their transcripts are immediately useful for meeting documentation, legal proceedings, and research analysis, without the manual effort of listening and tagging each speaker segment by hand.

## How it works

1. **Upload a multi-speaker recording** — Upload meetings, interviews, panels, or any recording with multiple participants.
2. **AI identifies each voice** — Our diarization engine analyzes voice characteristics to detect speaker changes and label each segment.
3. **Review and rename** — Speakers are labeled as Speaker 1, 2, etc. Rename them in the editor to use actual names.

## Capabilities

- **Voice Fingerprinting** — Each speaker's unique vocal characteristics are analyzed to maintain consistent labeling throughout.
- **Overlap Detection** — Handles crosstalk and overlapping speech, attributing words to the correct speaker.
- **Unlimited Speakers** — Works with 2-person interviews up to large panel discussions with 10+ participants.
- **Consistent Labels** — The same speaker is labeled consistently across the entire recording, even after long silences.

## FAQ

### How many speakers can it detect?

Blazescribe reliably identifies 2-10 speakers in a single recording. For larger groups, accuracy remains high for the most active speakers. Brief speaker introductions at the start of recordings improve accuracy for larger groups.

### Does it work with phone calls and video meetings?

Yes. Speaker identification works across all audio quality levels including phone calls, Zoom meetings, Teams calls, and in-person recordings. Higher audio quality produces better speaker separation.

### Can I rename speakers after transcription?

Yes. Speakers are initially labeled as Speaker 1, Speaker 2, etc. You can rename them in the editor and the new labels apply throughout the entire transcript instantly.

### How does it handle crosstalk?

Our AI is trained to handle overlapping speech. When two people talk simultaneously, the system does its best to attribute words to the correct speaker. Very heavy crosstalk may reduce accuracy in those specific segments.
