Let's Get Vocal About Disease

MP3 WAV

  • Alexa - tell me, do I have COVID-nineteen? Siri - am I developing dementia? Well, I can tell you that, Norbert! Ha! The thing is Dave, this is not a stretch. For the past decade, biotech companies have been developing voice analysis technology that can detect disease. And it's almost here! It's like I'm living in a Star Trek episode watching this crazy innovation move into reality.

    The technology uses artificial intelligence and machine learning to identify vocal biomarkers. These bio-signatures are present in dementia, depression, autism, and heart disease.

    When your body responds to disease, several systems become involved. For example, in early COVID infection, your lungs and larynx are both affected. In dementia or Parkinson's disease, speed of speech is changed and there's halting pauses as well as low volume.

    Researchers fed voice recordings from thousands of patients into computer algorithms that could analyze voices. AI and machine learning check for changes in speech patterns, intensity, tone and other features that become bio-signatures of the disease's impact on your speech. The accuracy in a number of studies already shows a detection rate of at least ninety percent.

    Alexa won't have the final word though. A doctor would have to make the official diagnosis, but virtual medicine may hit warp speed once this technology beams into our homes.

    What could be next?!

 Medicine...

Medicine is constantly advancing – that is a great thing about life in the 21st century. But it doesn’t just happen. Dedicated biomedical scientists are making discoveries that translate into those new medical advances.

Biomedical science is broad, encompassing everything from social science to microbiology, biochemistry, epidemiology, to structural biology and bioinformatics to name just a few areas. And, it can involve basic fundamental biology, the use of AI and chemistry to clinical studies that evaluate new medicines in patients.

No matter the research focus, the goal is always the same, to advance human health. It may take a few months, a few years or for fundamental science, a few decades. Few people make the connection that biomedical science is medicine and that biomedical scientists are working today on the medicine of tomorrow. Our weekly 500-word newspaper columns and 2-minute radio shows and podcasts provide insights into a broad range of biomedical science topics.

Medical Discovery News is dedicated to explaining discoveries in biomedical research and their promise for the future of medicine.
