⚙️ How Notta Speaker ID Works
🎬 Automatic Speaker Detection
Notta uses machine learning algorithms to automatically identify different speakers based on voice characteristics like pitch, tone, and speaking patterns. The system assigns generic labels (Speaker 1, Speaker 2, etc.) during transcription.
Detection Process
- • Voice activity detection
- • Speaker change identification
- • Voice characteristic analysis
- • Segment clustering
Audio Requirements
- • Clear audio quality
- • Minimal background noise
- • Distinct speaker voices
- • 3+ seconds per speaker
Output Format
- • Timestamped segments
- • Speaker labels (Speaker 1, 2...)
- • Confidence scores
- • Color-coded timeline
✏️ Manual Speaker Labeling
After transcription, users can manually assign names to each detected speaker. This process requires editing the transcript and is essential for creating meaningful meeting records.
Editing Process:
- 1. Open transcript: Access completed transcription
- 2. Click speaker label: Select generic Speaker 1, 2, etc.
- 3. Enter real name: Replace with actual participant name
- 4. Apply globally: Update all instances of that speaker
Best Practices:
- Use full names: John Smith vs John for clarity
- Consistent format: Same naming convention throughout
- Verify accuracy: Check speaker assignments before saving
- Save frequently: Preserve changes during editing
📈 Speaker Timeline Visualization
Notta provides a visual timeline showing when each speaker was active during the conversation, making it easy to see participation patterns and find specific discussions.
Timeline Features:
- • Color-coded speaker segments
- • Click-to-jump navigation
- • Speaking duration indicators
- • Overlapping speech visualization
- • Export timeline as image
