Voice and Resonance Disorders Flashcards
Aspects of voice
duration/time, pitch/frequency, loudness/intensity
Normal FF Women
200 hz
Normal FF Children
225-250 hz
Normal FF Men
125 Hz
Conversational Speech
60-65 dB
Puberphonia (Mutational falsetto)
pitch of voice does not change during puberty. Hormones impact vocal folds in men and women and change voice quality.
Resonance
quality of voice that is produced from sound vibrations in oral, nasal, and pharyngeal cavities.
Velopharyngeal Dysfunction
failure of velopharyngeal mechanism to separate oral and nasal cavities during speech. Cleft palate, all sounds are nasal.
Perceptual correlate of FF
vocal pitch
Perceptual correlate of intensity
vocal loudness
vocal misuse/abuse
anything too loud beyond capacity. Talking long time without rest, talking too loud, throat dryness.
vocal nodules (organic)
growths resulting from frequent, hard vocal fold collisions. Vocal abuse. Hoarseness and breathiness
vocal polyps (organic)
fluid filled lesions that develop when blood vessels rupture and swell.
sessile polyps
closely adhere to vocal folds and can cover two-thirds of the vocal fold. (more uniform rise and fall of vocal folds.)
Pedunculated polyps
appear to be attached by means of a stalk. (structure that looks like a mushroom. Stalk and larger structure)
Contact ulcers and granulomas (organic)
red ulcerations. ulcers heal and are replaced by granuloma. GERD
Laryngitis (organic)
Inflammation of the vocal folds that can result from exposure to noxious agents, allergies, or vocal abuse.
Papillomas (organic)
wart-like growths on vocal folds and interior larynx. HPV. Common in children younger than 6 years
Webs (organic)
connective tissue growth between vocal folds. must be removed surgically
Cancer (organic)
caused by cigs and alcohol. larynx is often entirely removed. esophageal speech (sphincters not vocal folds)
Damage to Vagus nerve (neurolgical)
vocal fold paralysis. Risk of aspiration when vocal folds are abducted.
Parkinsons Disease (neurological)
degeneration of neurons. classic symptom is short footsteps
Amyotrophic Lateral Sclerosis (Neurological)
A motor neuron disease characterized by degeneration of both the upper and lower motor neurons causing flaccid and spastic weakness. AAC device
Spasmodic Dysphonia (Neurologic)
damage to basal ganglia and cerebellar control circuits. voice tremors. can also be psychological and idiopathic. botox
Muscle Tension Dysphonia (Functional)
voice disturbance caused by abnormal muscle activity in absence of neurological and structural abnormalities.
Conversion aphonia (Functional)
caused by strong emotions. converting emotional conflicts into physical symptoms.
conversion aphonia
can cough to clear throat, but can’t speak.
Resonance disorders
can accompany voice disorders. Clefts, blokages in cavities
