Voice Disorders
About
A voice disorder is a disturbance of pitch, loudness, or quality
of the voice in relation to an individual's age, gender, or cultural
background. In the normal production of voice, the airstream is generated by
the lungs. As the air passes through the larynx, the vocal folds vibrate, which
results in the production of sound. The sound continues to travel through the
upper vocal tract and is modified by the resonating characteristics of the
pharynx and oral and nasal cavities.
Evaluation services
Videostroboscopy (LVS)—a technologically advanced system for viewing laryngeal
anatomy and physiology, which allows clinicians to view and analyze vocal fold
function including:
- stiffness
- irregularity of movement
- inappropriate closure
Computerized speech lab—a versatile speech-voice assessment
and therapy instrument—provides objective data about:
- pitch
- loudness
- duration
- degree of hoarseness
The data derived from these systems allow clinicians to consult with otolaryngologists
regarding a patient's vocal dysfunction, pathology, and/or performance
following surgery. The data also allow for the design of effective treatment
programs for clients with various voice disorders.
