Core Technology
Fireflies processes audio through multiple AI analysis stages:
- Neural Network Processing: Advanced speech recognition technology
- Voice Pattern Analysis: Unique voice characteristics identification
- Speaker Clustering: Groups similar voices together
- Timeline Mapping: Associates speakers with specific timestamps
Platform-Specific Features
✅ Google Meet & Zoom
- Shows actual participant names
- Calendar integration
- Auto-labeling from meeting roster
⚠️ Other Platforms
- Generic labels (Speaker 1, Speaker 2)
- Manual name assignment possible
- Voice pattern recognition still active
📊 Accuracy & Performance
🎯 Optimal Conditions
- 95%+ accuracy transcription
- Excellent speaker separation
- Real-time processing
- Clear voice distinction
⚠️ Challenging Scenarios
- Background noise interference
- Overlapping speech confusion
- Similar voices mix-ups
- Poor microphone quality
🚀 2025 Improvements
- Enhanced neural networks for better voice separation
- Improved cross-talk handling in fast-paced discussions
- Better accent recognition across diverse speakers
- Reduced speaker confusion in similar voice scenarios
🎛️ Key Features & Capabilities

⏱️ Real-Time
Live speaker identification during ongoing meetings
📝 Smart Transcripts
Organized by speaker with timestamps and context
⚠️ Current Limitations
- 🎪 Group meetings: Accuracy drops with 5+ simultaneous speakers
- 🗣️ Overlapping speech: Fast-paced interruptions can cause confusion
- 🌐 Accent variations: Heavy accents may reduce identification accuracy
- 🎙️ Audio quality: Poor microphones significantly impact performance
- 📱 Platform limitations: Generic labels on non-integrated platforms
💡 Best Practices for Optimal Results
✅ Do This
- Use good quality microphones
- Minimize background noise
- Speak clearly and at normal pace
- Use integrated platforms (Zoom, Google Meet)
- Allow brief pauses between speakers
❌ Avoid This
- Multiple people talking simultaneously
- Noisy environments or poor audio
- Extremely fast-paced conversations
- Very large group meetings (10+ people)
- Phone recordings with poor quality
