Speak into the mic for 10 seconds — no complicated setup, no musical training required. Your results appear instantly.
[Chart] 4-Axis Voice Quality Score
· Breathiness: how much air escapes versus clean tone
· Core: harmonic richness and vocal clarity
· Presence: energy in the 2–4 kHz "cut-through" range

All visualized on a radar chart so you see your voice's full shape at a glance.
