algorithm-based healthcareSonde Health contends that analysis of subtle changes in your voice can accurately reveal important aspects of your health. They are working to develop an algorithm that can be used to compare the vocal characteristics of an individual over time and use the data to develop correlates to mark the earliest onset of illness and disease. The company hopes to leverage their algorithm with machine-learning technology to provide a diagnostic and disease management solution.

Beyond the voice, there are opportunities to harness other signals to detect impending health problems. Early diagnosis is key in successfully treating many diseases. Changes in posture, gait, facial musculature, etc. could all be used as data points to develop systems that could monitor you on a regular basis and warn of abnormalities that could signal the need for medical/health intervention.
