Phonation

used to differentially diagnose MTD? Muscle Tension Dysphonia (MTD) is when a client has severe dysphonia and aphonia in the presence of normal or near normal appearing vocal folds. It is characterized by chaotic voicing and dysfunction during phonation. (Hancock, 2014). Since vocal presentation varies, the foundation of treatment can help manage a patient’s voice. There a multiple therapy approaches to treat a patient with MTD. Behavioral changes can be affected clinically, but clinicians need…

Singing begins with an exhalation of human vocal sounds (phonation) (NIDCD, 2015). At the point of phonation, two smooth adjacent muscle tissues in the thorax come into contact and vibrate to create resonating sound waves from the throat, mouth, and nose (NIDCD, 2015). As any vocal performer will confirm, singing is athletic, and to…

Abstract Respiration for life and respiration for speech while similar are very different. The two roles of the respiratory use the same structures and muscles yet they have very different outcomes. One results in breathing which is vital to life while the other produces sounds that make communication between two individuals easier. Therefore, the structures and muscles in the respiration for life help to deliver oxygen to the different parts of the body. Along with this, the main function of…

relying upon the site of injury. The sorts of dysarthrias are: Flaccid Dysarthria situated in the Peripheral nervous system or lower motor neuron. It disrupts the flow of neural impulses along the lower motor neuron that innervates the muscles of phonation,…

side of the vocal folds. When the vocal folds are inspected, vocal nodules appear as white protuberances. Protuberances are bumps located on the edge of the vocal fold, they occur here since this is the location that endures the most shock during phonation. As a result of these nodules, the individual may have a raspy and breathy voice. Aperiodicity, vocal fold vibrations that are not the norm, is a result of the additional weight on the vocal folds. To treat someone with vocal nodules,…

A lot of ideas taken from science play a part in vocal fold vibration. Both the Myoelastic Aerodynamic Theory and Bernoulli Effect deal with pressure and help to explain how vocal folds operate to create phonation. These processes can also be applied to real-life situations. The Myoelastic-Aerodynamic Theory describes the process of vocal fold vibration. It is important to recognize that the vibration of the vocal folds is the result of the interaction between tissue properties and airflow, not…

Susan’s main areas of difficulty involve motor speech, which affects her intelligibility. Particularly relating to the larynx, use of the tongue in speech and coordination of the lips and palate. This indicates that Susan is likely experiencing mixed spastic-ataxic dysarthria due to lesions on the upper motor neurone pathway (Wilkinson and Lennox 2005) in the corticobulbar tract which innervates the cranial nerves and the cerebellum (Bethoux et al 2013). Lesions on the upper motor neurone…

given that half her love must go to her husband. She thus responds to Lear’s command with “Nothing,” deeming her feelings on the matter “true” (1.1.96,119). By Hobbes’ philosophy, Cordelia actually spoke a falsehood in that “nothing” signifies the phonation of no words at all; in principle, she used the incorrect definition of the word by even speaking it in that context. This technicality did not prevent Lear, however, from declaring “Thy truth, then, be thy dower,” and disowning Cordelia…

causes VPI, or Velopharyngeal Insufficiency. “VPI is... inadequate closure of the Velopharyngeal Port.” This port is needed for both speaking and swallowing. So, someone with a VPI will usually have a very difficult time speaking because of a phonation problem, or a problem with making certain sounds and saying certain words, due to insufficient Velopharyngeal Closure or VPC (Blavati). When cleft palate or the Velopharyngeal Deficiency is repaired, many children have trouble with speech and…

Vocal Function Exercises (VFE) by Joseph Stemple Purpose: The Vocal Function Exercises (VFE) was invented by Joseph Stemple. The purpose of VFE is to balance the subsystems of voice production in order to improve and enhance the vocal function of the speakers with normal voices, opera singers, teachers with voice disorders, and elderly men (Stemple et al., 2014). Method: The VFE begins with describing the problem to the patient or showing illustrations using the patient’s own stroboscopic…
