Dysphonia vs. Dysarthria: What's the Difference?

Edited by Aimie Carlson || By Janet White || Published on February 2, 2024
Dysphonia is a disorder of voice quality, pitch, or volume, while dysarthria is a motor speech disorder affecting the physical production of speech.

Key Differences

Dysphonia refers to difficulties or changes in voice tone, where the voice may sound hoarse, weak, or breathy. Dysarthria, on the other hand, involves problems with the muscles that produce speech, leading to slurred or slow speech.
In dysphonia, the primary issue lies in the vocal cords or related structures in the larynx. In dysarthria, the issue originates from neurological impairments affecting speech muscles in the face, mouth, or respiratory system.
People with dysphonia often experience strain or discomfort while speaking, and their voice quality is affected. Those with dysarthria may have trouble controlling the pitch, volume, and rhythm of their speech.
Dysphonia can result from overuse of the voice, infections, or laryngeal diseases. Dysarthria is typically caused by neurological conditions like stroke, brain injury, or degenerative diseases.
Treatment for dysphonia may include voice therapy or medical intervention for the vocal cords. Dysarthria treatment often involves speech therapy focusing on improving muscle control and clarity of speech.
