The point prevalence of dysphonia in adults under the age of 65 is 6.6%. [20] Dysphonia is more common in adult females than males, [20] [42] possibly due to sex-related anatomical differences of the vocal mechanism. [4] In childhood, however, dysphonia is more often found in boys than girls. [43]

Dysarthria is a speech sound disorder resulting from neurological injury of the motor component of the motor–speech system [1] and is characterized by poor articulation of phonemes.

Muscle tension dysphonia (MTD) was originally coined in 1983 by Morrison [2] and describes a dysphonia caused by increased muscle tension of the muscles surrounding the voice box: the laryngeal and paralaryngeal muscles. [3] MTD is a unifying diagnosis for a previously poorly categorized disease process.
