UEP Podcast — Identifying Voice Disorders
In April 2024, Dr. James Thomas joined Dr. Shiying Hey on The UEP VoiceBox — the podcast of the Union of European Phoniatricians — for a wide-ranging conversation about how laryngologists actually listen to the voice. The episode, titled Identifying Voice Disorders, traces Dr. Thomas’s unusual path into laryngology and distills decades of clinical thinking into a few surprisingly accessible ideas about sound, pitch, and what a trained ear can hear before the endoscope ever enters the room.
From Physics to the Larynx
Dr. Thomas traces his interest in voice to high school, where a fascination with sound and physics set the direction for everything that followed. He completed both his undergraduate degree and medical school at Penn State, then six years of residency in Southern Illinois, before settling in Portland, Oregon. What distinguished his early career was what he calls his “wandering fellowship” — an informal tour of a dozen laryngologists around the world, culminating in six months studying with Bob Bastian in Chicago. That kind of apprenticeship-by-travel shaped a clinical philosophy grounded in direct observation and careful listening, rather than protocol alone.
Music has always run alongside the medicine. Dr. Thomas plays both piano and hammer dulcimer, and he is frank about how that ear for sound — for the overtones in a chord, for the moment a pitch wavers — informs the way he listens to a patient’s voice. The two pursuits, he suggests, are not as separate as they might seem.
The Three Sounds of a Voice
The 1990s brought a revolution in laryngology equipment — strobe lights that finally allowed clinicians to visualize the slow-motion mechanics of vocal fold vibration. But Dr. Thomas’s most consistent message in this episode is that the endoscope confirms what the ear should already suspect. Before anything touches the patient, he is listening.
He describes the voice in terms of three fundamental qualities: clear, husky, or rough. Each points toward a different class of problem. A husky voice suggests air leak — incomplete glottic closure, often from a mass or atrophy. A rough voice suggests irregular vibration — asymmetry, scarring, or a lesion disrupting the mucosal wave. Learning to distinguish these sounds, he argues, is not a matter of musical talent but of understanding what sound waves actually do, and what it means when they are disrupted.
The Pitch Glide — A Simple but Revealing Test
When Dr. Shiying Hey asks what someone can do at home to assess their own voice, Dr. Thomas’s answer is the pitch glide: a smooth, continuous change in pitch from low to high and back again. A catch — a moment where the voice breaks, cuts out, or suddenly changes quality — is a meaningful signal that something is interfering with normal vocal fold vibration. He suggests “Happy Birthday” as an easy, familiar melody that naturally traverses enough of the pitch range to stress-test the system. No musical training required.
In his clinic, he keeps a piano keyboard next to the endoscope. Asking a patient to match a tone on the keyboard is a reliable way to elicit the sounds that reveal the problem — particularly for patients who are unconsciously compensating and have learned to avoid the part of their range where the issue lives.
A Three-Part Workup
Dr. Thomas describes his clinical approach in three stages. First, the history — listening to how the patient describes what has changed, and when. Second, the voice examination itself — not just chatting, but methodically eliciting sounds at different pitches and volumes to stress the vocal folds and reveal where they fail. Third, the endoscopic examination, which confirms and refines what the ear has already suggested. The endoscope, in his framing, is the last step, not the first.
Compensatory Behaviors and Vocal Hygiene
The conversation turns at several points to compensatory phonatory mechanisms — the ways patients unconsciously adapt their voice production when something goes wrong. Dr. Thomas takes a nuanced view: compensation is not inherently bad. A singer who shifts technique to protect an injured fold may be doing exactly the right thing. The problem arises when the compensatory behavior becomes entrenched long after the original problem has resolved, or when it creates new tensions of its own.
On lifestyle, he is straightforward. Coffee and alcohol both reduce mucosal hydration, and a dry larynx is a less resilient one. He does not advocate for austerity, but for awareness — understanding that the voice, like any other tissue, responds to how the body is maintained. Hydration, vocal rest after heavy use, and avoiding unnecessary throat clearing are practical starting points for anyone who depends on their voice professionally.
Advice for the Next Generation
Asked what he would say to young clinicians drawn to laryngology, Dr. Thomas circles back to his earliest interest: learn about sound. Not necessarily music theory — though that helps — but the physics of how sound is produced and how it travels. An appreciation for what the voice actually is, acoustically, gives the clinician a framework for understanding what it means when something changes. Medical training supplies anatomy and pathology; the ear supplies the rest.
