What Affects Speaker ID Accuracy?
Helps Accuracy
- • Clear audio quality - Good microphones and quiet environment
- • Distinct voices - Different genders, accents, or speaking styles
- • Minimal overlap - Speakers taking turns, not talking over each other
- • Consistent speakers - Same people throughout the meeting
- • Longer conversations - More voice data to analyze patterns
Hurts Accuracy
- • Poor audio quality - Background noise, echo, low volume
- • Similar voices - Same gender, age, or speaking patterns
- • Frequent interruptions - Multiple people talking simultaneously
- • Short speaking time - Not enough voice data per speaker
- • Too many speakers - 10+ people makes identification harder
