Voice Flashcards
What is jitter?
variations in vocal fundamental frequency or fundamental frequency pertubation
What is shimmer?
variations in vocal fundamental frequency or fundamental frequency pertubation, but affecting amplitude or intensity of sound waves
When modifying a transgender person’s voice, consider the following factors:
increasing intonational variability; changing fundamental frequency; changing the upper and lower limits of the frequency range
What is indirect laryngoscopy?
a procedure in which a small mirror and light source is inserted through the mouth to view the larynx. A patient is not sedated and sits upright in a chair
What is direct laryngoscopy?

What is a videostroboscopy?
a strobing light that records the vocal folds during vibration
What are differences between a flexible fiber optic laryngoscopy and a endoscopy?
With a flexible fiber optic laryngoscopy, one can view the vocal folds while the person is speaking and it is passed through nasally. An endoscope can be passed through the mouth or the nose and you can view the anatomy and physiology of the larynx
What is videokymyography?
taking pictures and videos of the vocal folds moving
What is the difference between an electroglottography (EGG) and electromyography (EMG)?
EGG is noninvasive and used to see how VFs open and close by putting electrodes on both sides of the thyroid cartilage; EMG is invasive and used to see patterns of VF activity by putting a needle in the laryngeal muscles
What are the differences between vocal nodules and vocal polyps?
Nodules are unilateral or bilateral, may require surgery, and can result in breathy, hoarse, or low pitch voice. Vocal polyps are unilateral and can result in diplophonia, breathy voice or hoarse voice
What is cul-de sac resonance?
a muffled or hollow sound due to the tongue being retracted all the way back which blocks part of the back of the oral cavity
What are voice symptoms associated with multiple sclerosis?
Since MS results in demyelination of white matter, a patient can have artic breakdowns, breathy and harsh voice, hypernasal, impaired prosody and unable to control pitch and loudness.
What are voice symptoms associated with myasthenia gravis?
Since myasthenia gravis is associated with a decrease in acetylcholine leading to muscle weakness and fatigue, symptoms include hypernasality, soft sounding voice, breathy, and hoarse; dysphagia may be present too
What parts of the vocal folds are considered the body?
