Status: Pre-IEC feasibility pilot in preparation · Google.org AI for Science application submitted May 2026
No validated AI tool exists for detecting depression in Hindi-speaking populations using speech. Existing speech emotion recognition models achieve only 58–62% accuracy on Hindi speakers because all corpora use simulated, non-clinical speech. No naturalistic, clinically-labelled Hindi depression speech dataset exists anywhere in the world.
MANAS-AI will create that dataset and develop the first validated AI screening model for Hindi-language depression detection — deployable by community health workers on a smartphone, without requiring a specialist at the point of contact.
A three-step research-to-deployment pathway
250–300 psychiatric OPD patients at IHBAS Delhi and VIMS Uttar Pradesh complete three structured speech tasks (~4 minutes). Each recording is labelled with PHQ-9 score and ICD-10 diagnosis as ground truth.
Acoustic features extracted using openSMILE eGeMAPS and Praat. SVM, Random Forest, and XGBoost classifiers trained on labelled data. Validated against PHQ-9 benchmark (target: ≥75% sensitivity, ≥80% specificity).
Validated model integrated into Medijunction Swasthya Didi platform. Community health workers in Alwar District, Rajasthan conduct 4-minute speech screening using a smartphone. Screen-positive individuals referred for teleconsultation.
MANAS-AI is delivered through a collaboration spanning clinical psychiatry, speech AI methodology, and community field deployment
