Spasmodic dysphonia, also known as laryngeal dystonia, is a disorder in which the muscles that generate a person's voice go into periods of spasm. [1] [2] This results in breaks or interruptions in the voice, often every few sentences, which can make a person difficult to understand. [1]
Voice problems that require voice analysis most commonly originate from the vocal folds or the laryngeal musculature that controls them, since the folds are subject to collision forces with each vibratory cycle and to drying from the air being forced through the small gap between them, and the laryngeal musculature is intensely active during speech or singing and is subject to tiring.
Aphonia is defined as the inability to produce voiced sound. [1] This may result from damage, such as surgery (e.g., thyroidectomy) or a tumor., [2] or can be a result of psychological means. Aphonia means "no sound.” In other words, a person with this disorder has lost their voice and is unable to communicate vocally. [3]
The spasms sometimes make the vocal cords very tight, making the voice sound strained. When the vocal cords come apart, the voice sounds breathy. At any time, the voice can go from a soft, breathy ...
Among vocal pedagogues and speech pathologists, a vocal register also refers to a particular phonation limited to a particular range of pitch, which possesses a characteristic sound quality. [12] The term "register" may be used for several distinct aspects of the human voice: [ 8 ]
Surgical technique(s) to improve the human voice by altering single or multiple structures of the larynx, which houses the vocal folds (vocal cords) with the related controlling nerves, muscles, and cartilage. Typically, this surgery is considered to improve the position or tension of the vocal folds which can improve vocal volume and production.
Egophony (British English, aegophony) is an increased resonance of voice sounds [1] heard when auscultating the lungs, often caused by lung consolidation and fibrosis.It is due to enhanced transmission of high-frequency sound across fluid, such as in abnormal lung tissue, with lower frequencies filtered out.
Voice disorders can be divided into two broad categories: organic and functional. [9] The distinction between these broad classes stems from their cause, whereby organic dysphonia results from some sort of physiological change in one of the subsystems of speech (for voice, usually respiration, laryngeal anatomy, and/or other parts of the vocal tract are affected).
