Voice Disorders
Voice quality, pitch, and loudness are all significant attributes of speech. Inefficient vocal mechanism use such as vocal fatigue; muscle tension dysphonia or aphonia; diplophonia; ventricular phonation warrants concern for a voice disorder. Vocal nodules is a type of voice disorder that is cause by behavioral voice misuse. Speech-language pathologists (SLPs) may also be involved in the assessment and treatment of disorders that affect the voice mechanism.
