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
Voice therapy is commonly used in the treatment of MTD. [7] The goal of voice therapy is to encourage proper vocal used and decrease the tension of the laryngeal muscles. [ 15 ] Examples of voice therapy include voice exercises to help increase glottic closure, vocal hygiene, manual laryngeal therapy, respiratory exercises, nasal exercises and ...
Voice disorders range from aphonia (loss of phonation) to dysphonia, which may be phonatory and/or resonance disorders. Phonatory characteristics could include breathiness, hoarseness, harshness, intermittency, pitch, etc. Resonance characteristics refer to overuse or underuse of the resonance chambers resulting in hypernasality or hyponasality ...
Vocal cord dysfunction (VCD) is a condition affecting the vocal cords. [1] It is characterized by abnormal closure of the vocal folds, which can result in significant difficulties and distress during breathing, particularly during inhalation.
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
One example of such stress is the impact stress caused by the collision between the left and right vocal fold surfaces during vibration. [2] This stress is thought to reach its maximum in the mid-membranous region of the vocal folds, at the junction of the anterior 1/3rd and posterior 2/3rd, the most common site of nodule formation.
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]
[4] [5] Though voice qualities may appear normal in some cases of vocal fold paresis or paralysis, [3] mild differences in tension between the two vocal folds of the larynx can result in changes of voice pitch, intensity and reduced vocal stamina. [6] [5] Patients with either vocal fold paresis or paralysis may exhibit a breathy voice quality.
