Voice: The 5th Vital Sign with Dr. Kang Hsu
Description
In this episode, Dr. Mark Bonta sits down with Dr. Kang Hsu, Chief Medical Officer of Canary Speech, to explore how AI and vocal biomarkers could make the human voice the next vital sign in medicine.
They unpack the science behind this breakthrough, showing how subtle shifts in tone, rhythm, and cadence can reveal early signs of depression, anxiety, Parkinson’s, or cognitive decline long before symptoms appear.
Dr. Hsu shares the origin story of Canary Speech, the research that powers its models, and how voice-based screening is already being used in healthcare, from telehealth visits to smart devices.
It is a look into a future where a 40-second voice sample could help doctors detect disease, personalize treatment, and bring empathy back into digital medicine.

1. Voice as a Vital Sign
Your voice holds more data than you realize. Subtle changes in tone and rhythm can reveal early signs of depression, anxiety, or even cognitive decline.
2. Objectivity Through AI
Canary Speech uses vocal biomarkers to turn speech into measurable data, giving clinicians objective insight where surveys and self-reporting fall short.
3. New Frontiers in Telehealth
Voice analysis can run quietly in the background of virtual visits and smart devices, creating a noninvasive way to monitor mental and physical health between appointments.
4. The Challenge of Change
Healthcare moves slowly. Adoption depends on awareness, trust, and showing how accessible technology like this can ease strain on overburdened systems.
5. A Future Built on Listening
In time, voice may join heart rate and blood pressure as a standard vital sign. It can help detect disease earlier and make care more personal, not less.
