Need for Replication, Validation
Commenting on the findings, John Torous, MD, director of the division of digital psychiatry at Beth Israel Deaconess Medical Center, Boston, noted that “over the last 20 years, there has been a lot of interest in voice biomarkers, yet somehow that research has never been translated into mainstream clinical care.”
Voice biomarkers are “relevant and have potential” in mental health, he noted. The findings in this study are “interesting, but they need to be thoroughly externally replicated and validated to show that these biomarkers are valid and reliable,” Dr. Torous added.
Changes in voice are part of the mental status exam, Dr. Torous said, “but it’s only one piece of information that we collect in a clinical assessment of many pieces of information.”
Dr. Torous also cautioned that “as a practicing psychiatrist, it can be tricky to be given new data if you don’t know how to interpret it or what it means. An important step would be education, outreach, and resources for physicians to learn about potential voice biomarkers.”
