Sonde Health is a Boston-based digital health company that turns short voice samples into vocal biomarkers — objective, AI-derived measures of respiratory, mental and cognitive fitness. Founded out of PureTech Health, Sonde has banked over 1,000,000 voice samples from more than 80,000 subjects to train its Health Check models. Partners integrate through the Sonde Platform Service API (a HIPAA-aligned REST API on api.sondeservices.com secured with OAuth 2.0 client-credentials and fine-grained sonde-platform/* scopes), through on-device Passive, Cued and Edge SDKs for Android and iOS, and through OEM integrations such as Qualcomm's Snapdragon Sound platform. The cloud flow is upload-and-score: register a subject, request a signed storage URL, upload a WAV sample, then create an inference job and poll for Respiratory Symptoms Risk, Mental Fitness voice-feature scores, M3/PHQ-2 questionnaire scores, or an English transcription.
