What is Muscle Tension Dysphonia (MTD)?

Muscle tension dysphonia (MTD) is often described as an achy feeling in the throat, voice fatigue, or loss of vocal endurance. For singers, teachers, speakers, and other vocal professionals, this can be frustrating and very limiting. Voice rest may make the problem worse, making symptoms even more perplexing.

What is muscle tension dysphonia?

Dysphonia simply means problem with the voice. MTD is diagnosed when voice symptoms are due to muscular tightness or inefficiency. MTD occurs when the muscles surrounding the voice box interfere with efficient vocal function. The voice that may sound strained, breathy, weak, or fatigued. Some people feel like they’re “pushing” to speak, or like their voice gives out by the end of the day.

What makes MTD tricky is that it often occurs without any structural damage to the vocal folds. That means standard exams may not detect it unless a specialist trained in stroboscopy and laryngeal function is involved.

Common Triggers Include:

• Stress and anxiety

• Overuse or use during periods of illness or inflammation

• Improper vocal technique

• Underlying vocal injury

Despite increased effort to close (shown by false vocal fold squeeze (1) and base of tongue/epiglottis (2) compression), the vocal folds themselves are not closing well (3), demonstrating a common finding in MTD.

Why Early Diagnosis Matters

Left untreated, MTD can cause disabling symptoms of fatigue and voice pain. The earlier it's identified, the easier it is to resolve through targeted voice therapy and proper technique.

Laryngeal massage is a key additional strategy to resolving the problem but must be done by an expert in laryngeal manual techniques.

At the Center for Vocal Health, we specialize in diagnosing and treating MTD in professional voice users. If your voice feels “off” but your exam looks normal—MTD might be the missing piece.
