Pacing (Target 110–140 WPM): Your speaking speed. Speaking at 110–140 words per minute helps you reach the minimum goal of 80 words in 45 seconds without rushing.
Pitch change (Target 25–40%): Measures how much your voice goes up and down. A range of 25–35% helps you sound natural and interesting, rather than flat and boring (near 0%) or too unstable (over 50%).
Flow Rate (Composite Target >75%): Automatically weights total pause time, frequency of mid-phrase interruptions, filler counts, and restarts alongside your speech rate (phonation ratio) into a unified score.
- Pauses: Short pauses (>0.8s mid-phrase) and long pauses (>2.5s long dead air any time).
- Fillers: Spoken markers like "um" and "uh".
- Restarts: Mid-sentence self-corrections.
