Speaking Pace by Industry

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 Word Frequency by Role

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.

Eye Contact Distribution

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%

Source: Journal of Nonverbal Behavior. Eye contact engagement directly correlates with audience trust and retention.

Understanding Public Speaking Anxiety

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)

Methodology

Benchmarks are calculated from aggregate, anonymized data collected across Stageum's platform between January 2024 and May 2026. All metrics are derived from AI-powered real-time analysis using webcam and microphone input, processed locally in the browser via TensorFlow.js and the Web Speech API. Only users who have completed 3+ sessions are included in the averages. Individual results vary based on starting skill level, practice frequency, and session length.
