Average speaking pace varies significantly by professional context. Executives tend to speak more deliberately, while sales professionals typically speak faster to maintain energy. The optimal range for clarity and engagement is 140-160 WPM.
| Industry | Average Pace (WPM) | vs Optimal |
|---|---|---|
| Executive | 142 WPM | Within range ✓ |
| Sales | 156 WPM | Within range ✓ |
| Academic | 138 WPM | Slightly below range |
Reference: National Center for Voice and Speech identifies 150-160 WPM as optimal for audience comprehension. TED Talks average 163 WPM.
Filler words ("um," "uh," "like," "you know") significantly impact perceived competence. Research shows a threshold of 5 filler events per minute or fewer does not damage effectiveness, while 12+ per minute measurably reduces audience engagement.
| Role | Filler Words/Min | Assessment |
|---|---|---|
| Academic | 3.9 | Good ✓ |
| Executive | 4.8 | Good (below 5/min) ✓ |
| Sales | 6.2 | Needs improvement |
Sources: PubMed 2024 filler word impact study, Stageum platform aggregate data. Cal Poly study found speakers rated 5.93/7 without filler words vs 3.99/7 with fillers.
Effective public speakers distribute their gaze across three zones: direct engagement with audience members (or camera), scanning across the room, and occasional reference to notes. Stageum's AI tracks these patterns in real time.
| Gaze Type | Percentage | Recommendation |
|---|---|---|
| Direct (camera/audience) | 60-70% | Target 70%+ for high stakes |
| Scanning (across audience) | 20-25% | Healthy range ✓ |
| Downward (notes/floor) | 5-15% | Keep under 10% |

Public speaking anxiety affects a significant portion of the population. Research indicates approximately 21.2% of the US population and 49% of the UK population experience significant speech anxiety. Regular practice in realistic environments has been shown to reduce anxiety through exposure therapy and confidence building. (Sources: PubMed 2024, Journal of Anxiety Disorders)
