Study establishes link between coronary artery disease and voice

Beyond Verbal announced the results of a new study on Coronary Artery Disease (CAD) patients, conducted together with the Mayo Clinic. The research shows that voice analysis can be used to identify the presence of CAD by establishing a strong correlation between certain voice characteristics and CAD. The study represents a significant breakthrough in this field, proving that there is a connection between distinct voice features and health conditions, which can significantly improve continuous monitoring and reduce remote healthcare costs.

CAD is one of the leading causes of cardiovascular mortality worldwide. When screening for the disease, there was a great need for simple and noninvasive tests that could also improve the accuracy of risk estimation models. This is where Beyond Verbal realized they could use their technology to provide unique insight. In the past, Beyond Verbal has found voice signal characteristics that can be associated with various conditions such as Autism and Parkinson’s. The company then joined forces with Mayo Clinic in order to research this same concept with CAD patients.

After conducting the double blind study, which included 120 patients referred for elective coronary angiography and corresponding control subjects, one voice feature was shown to be associated with a 19-fold increased likelihood of CAD. This is the world’s first study to suggest a link between voice characteristics and CAD, and hold the potential to assist physicians in estimating the pre-test probability of CAD amongst patients with chest pain.

Yuval Mor, CEO of Beyond Verbal: “A patient’s voice is the most readily available, easy to capture, and rich output the body offers. We are very excited to be able to work with Mayo Clinic on such a breakthrough research, studying the potential of using the human voice in healthcare monitoring and specifically CAD.”

Beyond Verbal has recently announced the availability of the Beyond mHealth Research Platform to facilitate the global collaboration between hospitals, research institutes and universities in the research to find vocal biomarkers.During the past 21 years, Beyond Verbal has collected more than 2.5 million emotion-tagged voice samples in more than 40 languages to analyze human emotions. Working off the concept that vocal intonation can provide significant insight into the inner-workings of human beings, the company is expanding its research on the connection between vocal intonations and health issues.
