Grounded in clinical acoustics
Breath Vision listens the way pulmonologists do — reading the time-frequency shape of breath and voice, then translating it into plain language.
Six signals
Cycles per minute at rest. Elevated rates can suggest exertion, anxiety or airway resistance.
How long you can sustain /a/ on one breath — a proxy for vital capacity and vocal control.
Steadiness of pitch and amplitude across sustained vowels — reflects laryngeal control.
Rapid repetition of pa-ta-ka. Slower rates can indicate reduced articulatory coordination.
Ratio of inspiration to expiration. Extended expiration can suggest obstructive patterns.
Timbre and reflex quality of voluntary coughs, useful for surfacing wet vs. dry patterns.
Four classes
Continuous, high-pitched sounds. Often associated with narrowed airways.
Short discontinuous clicks. Fine crackles suggest small-airway reopening.
High-pitched, usually on inspiration. May suggest upper airway narrowing.
Low-pitched, continuous sounds. Often linked with mucus in larger airways.
Where each sound lives
The shape of a healthy breath
A resting cycle has a quick inhale, brief pause, and a longer controlled exhale — the timing itself is a clinical signal.
