40-SECOND VOICE SCREENING
Every 3 seconds,
someone develops
dementia.
26 million Indians. Zero screening tools built for them. Until now.
187 biomarkers from voice, eyes, cognition and brain activity. Twelve minutes on any smartphone. No hardware. No English required.
AFFILIATIONS & ASSOCIATIONS
THE CRISIS
Drugs exist. Blood tests exist. Nobody finds patients early enough.
Current screening requires a clinician, English literacy, and a hospital visit. Hundreds of millions have access to none of these.

HOW IT WORKS
Ten signal streams. One twelve-minute session.
Each stream measures a different part of the brain. Read together, they separate normal ageing from impairment from dementia.
Voice
Jitter, shimmer, prosody and articulation from natural speech in any language.
biomarkers
per session
Any smartphone
No hardware to buy. Camera, mic and touchscreen carry eight of ten streams.
Any language
Tasks use pictures, colours and numerals. Zero literacy required.
Twelve minutes
Fits inside an existing OPD visit. No extra staff time.
INDEPENDENT VERIFICATION
Built on published science. Not claims.
Every signal traces to peer-reviewed work. The accuracies below are literature ceilings for multimodal fusion, validated against our SGPGI cohort.
