Sonde Health using voice as a biomarker for diagnosis

Back in 2013, we profiled Max Little of the UK-based Parkinson’s Voice Initiative, who was in the fairly early stages of voice testing and analysis to aid early diagnosis of this disease. By 2015, he had over 17,000 voice samples, was partnering with the Michael J Fox Foundation, and was seeking to develop a non-invasive, quick, accurate test based on acoustic markers. Dr Little is an Oxford University PhD, currently a Wellcome Trust/MIT fellow at the MIT Media Lab. The Voice Initiative has additional support from PatientsLikeMe, Twilio and Aculabcloud.  But also developed at MIT, by Thomas Quatieri’s team at MIT’s Lincoln Laboratory, is a broader platform for voice diagnosis. This has been applied to mental health conditions such as depression, respiratory and cardiovascular conditions, and in pilots for TBI, cognitive impairment and…Parkinson’s. This has been licensed to Sonde Health, which hasn’t much on their website but is out of the Boston-based PureTech R&D/venture firm. The acoustic markers they cite are ‘dynamic changes in pitch and harmonics, articulation timing and hoarseness or breathiness that indicate and requires no analysis of words’.
