Sonde Health builds a vocal biomarker platform that uses advanced audio signal processing, speech science and AI/machine learning to detect subtle vocal changes tied to physiology. The company maintains a health‑labeled voice dataset of over 1.2 million samples from more than 85,000 subjects across four continents. Sonde offers enterprise products and licenses its platform for telehealth, pharma, remote patient monitoring, and consumer/medical devices, and it can embed technology into device chipsets for passive monitoring. Its Health Checks include respiratory fitness (detects conditions like asthma from six seconds of voice; users engage 2+ times per week) and mental fitness (detects signs of depression and anxiety from 30 seconds of voice; users engage 3+ times per week). Sonde is developing additional vocal biomarkers for MCI, COPD and general health using a research‑build‑validation methodology with clinical partners. The company intends to deepen its respiratory and mental health monitoring, expand into new health conditions and geographies, and accelerate commercial growth using the new funding. Sonde Health is developing a voice-based technology platform that uses acoustic analysis of seconds of voice to generate vocal biomarkers and persistent brain, muscle, and respiratory health measurements. Its proprietary technology is designed to run on consumer devices such as smartphones and smart speakers to enable disease screening and management. The company reports it has collected voice and health data from over 10,000 subjects as part of ongoing platform validation. Sonde intends to expand its technology across multiple health conditions and device types and to accelerate validation into neurological, respiratory, and cardiovascular diseases as well as other health and wellness conditions. The company plans to commercialize its offerings to provide broader access to timely health information and support new models of precision and preventative medicine. The announcement was datelined Boston and notes that Sonde was co-founded by PureTech Health.
