Voice analysis specialist Beyond Verbal and Mayo Clinic unveiled results from a new study demonstrating a strong correlation between some voice characteristics and the presence of coronary artery disease (CAD).
Beyond Verbal, which bills itself as an emotions analytics company, focuses on extracting as much information as possible from the tone of voice of a speaker, said CEO Yuval Mor. Voice analysis may be used to understand emotions and well-being, he said. We can tell with the human ear, for example, if a person is feeling well or not. The new study data confirms that we can also understand a medical condition by using voice feature analysis.
The double-blind study involved 120 patients who had been referred for elective coronary angiography and 120 control patients. Beyond Verbal provided Mayo Clinic with acoustic features, and the latter zeroed in on some characteristics that could “strongly and independently” be associated with CAD, Mor said. In particular, one feature was linked to a 19-fold higher likelihood of CAD, the companies said in a statement.
