Beyond Verbal recently used its emotion-detecting voice analysis app in an attempt to predict coronary artery disease in 150 study participants, 120 of whom had presented for angiography. The company claims to have identified 13 voice features associated with CAD – and one associated with a 19-fold increase in its likelihood.
The researchers said that the voice indicator was strongest when a subject described a negative experience. As this suggests an emotional connection to heart disease, could a neurotech wearable, that provides brain activity analysis, validate the process? The company is already studying voice changes in Autism and Parkinson’s disease, but this was the first time they used their voice diagnostic tool in a non-brain disease study.
