Voice Disorders

Voice disorders occur when the vocal folds (commonly called vocal cords) do not vibrate efficiently, producing a voice that sounds hoarse, breathy, strained, too high or too low, too loud or too soft, or otherwise different from what is expected for the individual's age and sex. Voice disorders can be organic (caused by structural or neurological changes) or functional (resulting from vocal misuse or muscle tension without underlying structural pathology).

Common organic voice disorders include vocal fold nodules (callous-like growths from chronic vocal abuse), polyps (fluid-filled lesions often caused by a single traumatic vocal event), vocal fold paralysis or paresis (reduced movement due to nerve damage), laryngopharyngeal reflux (irritation of the vocal folds from stomach acid), and age-related vocal changes (presbyphonia). Neurological voice disorders include spasmodic dysphonia and tremor.

Functional voice disorders, including muscle tension dysphonia (MTD), are among the most common voice problems seen in clinical practice. MTD occurs when the muscles of the larynx and surrounding structures become excessively tense during voicing, producing a strained, effortful vocal quality. Teachers, singers, coaches, lawyers, and others who rely heavily on their voices are at elevated risk for both organic and functional voice disorders.

Voice problems can develop gradually or suddenly and may fluctuate in severity throughout the day or across situations. Any voice change that persists for more than two to three weeks should be evaluated, first by an otolaryngologist (ENT) to examine the vocal folds and then by a speech-language pathologist specializing in voice therapy.

Many people adapt to gradual voice changes and may not recognize how significantly their voice has been affected until it begins to interfere with work, social interactions, or daily activities. Early intervention produces better outcomes and can prevent conditions from worsening.

Voice therapy begins with a comprehensive voice evaluation that includes perceptual assessment of vocal quality, acoustic analysis using specialized software, aerodynamic measures of airflow and pressure, and a detailed vocal use history. We coordinate closely with otolaryngologists and review laryngoscopy (visualization of the vocal folds) findings to ensure our therapy plan addresses the specific underlying condition.

Our therapy approaches are evidence-based and tailored to the individual's diagnosis and vocal demands. For muscle tension dysphonia, we use laryngeal reposturing techniques, circumlaryngeal massage, resonant voice therapy (Lessac-Madsen Resonant Voice Therapy), and vocal function exercises to reduce tension and promote efficient voicing. For vocal fold lesions, therapy focuses on eliminating the abusive vocal behaviors that caused the lesions while teaching healthy voice production techniques.

For professional voice users, including teachers, singers, actors, and executives, we provide targeted vocal hygiene education and voice optimization strategies. We help clients identify and modify the vocal behaviors that contribute to their voice problems, including excessive throat clearing, speaking loudly in noisy environments, inadequate hydration, and poor breath support.

Lee Silverman Voice Treatment (LSVT LOUD) is our primary approach for individuals with Parkinson's disease and other neurological conditions that affect voice. LSVT LOUD is an intensive, highly structured program with strong evidence for improving vocal loudness and intelligibility in this population.

We also provide pre- and post-surgical voice therapy for clients undergoing vocal fold surgery. Presurgical therapy optimizes vocal habits before the procedure, while postsurgical therapy guides the gradual return to voice use and helps the client develop healthy vocal techniques for long-term vocal health.

The voice evaluation typically takes 60 minutes and includes a comprehensive case history, perceptual voice assessment, acoustic and aerodynamic measurements, and review of your ENT examination results. We discuss our findings and recommend a personalized therapy plan tailored to your specific voice disorder and vocal demands.

Voice therapy sessions are typically 45 minutes, once or twice weekly, for a course of six to twelve weeks depending on the diagnosis and severity. Each session includes direct voice exercises, techniques for carryover into daily communication, and education about vocal hygiene and voice care. Many voice disorders respond well to therapy alone, without the need for surgical intervention.

We track progress through pre- and post-treatment voice recordings, standardized self-assessment questionnaires (such as the Voice Handicap Index), and objective acoustic measures. Our goal is to help you achieve a voice that feels comfortable, sounds like you, and meets the demands of your personal and professional life.
