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]
Puberphonia is a functional voice disorder [citation needed]. To rule out problems in the structure of the larynx as the cause of their voice issues, patients are often referred to otorhinolaryngologists for a physical examination of the larynx and vocal folds. Once physical pathologies are ruled out, a behavioural evaluation can occur. [6]
Voice disorders [1] are medical conditions involving abnormal pitch, loudness or quality of the sound produced by the larynx and thereby affecting speech production. These include: These include: Vocal fold nodules
Spasmodic dysphonia is a neurological disorder that causes involuntary spasms in the muscles of the voice box, also known as the larynx. The condition means vocal cords don't vibrate normally.
The most common types of dysprosody are associated with dysarthria and developmental coordination disorder, which affect motor processing in speech. Among the most studied types are: Flaccid dysarthria is characterized by little control over pitch and voice volume, reduced speech rate, and impaired voice quality
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).
Presbylarynx is a condition in which age-related atrophy of the soft tissues of the larynx results in weak voice and restricted vocal range and stamina. In other words, it is the loss of vocal fold tone and elasticity due to aging which affects voice quality.
The delays and disorders can range from simple sound substitution to the inability to understand or use one's native language. [3] In general, communication disorders commonly refer to problems in speech (comprehension and/or expression) that significantly interfere with an individual's achievement and/or quality of life.
