Researchers have found biomarkers in the voice that identify certain diseases, including mental health disorders, central nervous system problems, and even heart issues!
What can be detected in a voice? Emotions? Our physical state? Our level of confidence? Yes to all!
Makes sense, right? If we feel sanguine or sad, others know it after only hearing us speak a few words. Likewise, if we are worn out or wired, self-assured or filled with self-doubt, our voices tell the tale.
But would you believe that researchers are exploring ways that our voices can indicate disorders and diseases? They have identified people with post-traumatic stress disorder, coronary artery diesase, Parkinson’s disease, depression, and other problems. They use voice biomarkers, which are acoustic measures of the voice signal.
Blood, Urine and VOICE SAMPLE?
As you talk to Siri or Alexa, consider that someday your voice might be used as a key indicator of your health. Currently, you may use your voice to initiate web searches, operate devices, and connect with others. But imagine that for a routine physical, you have blood drawn, vitals taken, and finally, submit a voice sample for acoustic analysis!
I am an ASHA-certified speech-language pathologist (SLP) passionate about voice. Over the years, I have investigated a dizzying number of acoustic voice measures. But even with all of this data, we have yet to find definitive identifiers of specific voice disorders. However, SLPs are often the first professionals to suspect neurological diseases like Parkinson’s. We are experienced in listening to the voice characteristics that often accompany this disease: For instance, we may notice fast rushes of speech, reduced loudness, and reduced precision of articulation that are hallmarks of Parkinson’s disease. We have been trained to use our ears for this rather than acoustic analysis.
Therefore, I wonder about the measures used in the studies mentioned above. I will be diving deeper into the research, and will tell you more as I learn.
