Signal clarity should reflect your voice, not fans, music or echoes.
Overacting or forcing depth makes the profile less representative.
Treat results as practice feedback, never as a verdict on attractiveness.
Attractiveness is subjective and cannot be reduced to pitch. Rather than inventing a scientific-looking total score, this tool exposes the acoustic traits it can actually estimate.
Steadiness uses pitch variation, clarity uses measurement confidence and expression uses effective semitone movement. Articulation, warmth, language, emotion and listener preference remain outside this browser measurement.
No universal scientific score exists. Preferences vary by listener, culture and context.
