Problem
The narration repeats information already communicated by on-screen text, doubling audio processing without adding value.
Solution
Root Cause / Diagnostic:
Redundantly reading verbatim on-screen text insults viewer intelligence and doubles cognitive processing load without providing new context. Audiences read faster than human speech; verbatim repetition creates perceptual sluggishness and prompts rapid scrolling.
Actionable Fix:
1. Complement Rather than Mirror Text: Ensure on-screen graphics display high-level summaries, statistics, or keywords while the narration provides underlying context, analysis, or nuance.
2. Restrict Text Overlays to 3–5 Core Words: Condense visual cards to concise data points or provocative labels rather than full sentences spoken by the presenter.
3. Validate Dual-Channel Efficiency: Review the timeline to verify that text overlays add distinct visual value rather than echoing voiceover verbatim.
Pro Tip:
Use the "Rule of Complementary Channels": Let the graphic show the metric (e.g., "+34% Growth") while the audio explains the strategic reason behind the metric.
