Detected frames divided by analyzed frames. Pauses reduce coverage; this is not speech clarity, accuracy or voice quality.

Review pitch variation and span, then listen back independently. Listener attraction cannot be calculated here.
Only pitch measurements are reported. There is no attractiveness, clarity or expression rating.

Overacting or forcing depth makes the profile less representative.
Treat results as practice feedback, never as a verdict on attractiveness.

A wider span means more detected pitch movement, not greater attractiveness. Coverage never measures articulation.

Read the measurement guideAutocorrelation analyzes 2,048-sample frames about every 45 ms, within 60–400 Hz. Frames need RMS ≥ 0.01 and correlation ≥ 0.55. A result requires 20 detected frames and at least 20% detection coverage.
Median, mean and standard deviation use detected frames. Endpoints are the 2nd and 98th percentiles; trimming extremes does not guarantee removal of octave errors.
Microphones, noise and octave errors affect results. Accuracy has not been independently validated. Pitch bands are interface descriptions, not population norms or diagnoses.
These tools share one pitch detector; each page offers a different way to interpret its measurements.
No universal scientific score exists. Preferences vary by listener, culture and context.
Only pitch measurements are reported. There is no attractiveness, clarity or expression rating.
Use a quiet room, comfortable breath support, clear articulation and a natural pace. Do not force a lower pitch.
No. Expressive variation can be engaging. The traits are descriptive, not a ranking of personal worth.
