Voice analyzer
live demoLive pitch, clarity and spectrum while you hum — measured against your own baseline, on your device
PRD F8 · Phase 2–3
Everything runs in your browser — nothing recorded, nothing uploaded. It tracks the acoustic signals voice clinicians listen for, live, as you hum. Consumer mics and automatic gain control make absolute values untrustworthy, so every number here is framed against YOUR baseline, never a universal scale.
🎙️
Hum a comfortable note. Watch the harmonics stack on the spectrogram, set a baseline, then try to come back to it — real-time visual-acoustic biofeedback, the seed of the future listening coach.
Why these four numbers
Pitch and steadiness are the trainable basics — where your voice sits and how well it holds. Clarity is the signal clinical listening keeps coming back to for overall voice health; the published thresholds for it come from calibrated lab equipment, which is exactly why we show your trend and never a verdict. Tone balance hints at breathiness. And the picture tells the same story: a healthy hum draws an evenly spaced ladder of harmonics — watching that ladder blur is what breathiness looks like.
