Dysprosody is "characterized by alterations in intensity, in the timing of utterance segments, and in rhythm, cadency, and intonation of words." These differences cause a person to lose the characteristics of their particular individual speech. While the individual's personality, sensory comprehension, motor skills, and intelligence all remain intact, their grammar as well as vocal emotional capacity can be affected. Prosodic control is essential to speech delivery because it establishes vocal identity, since each individual's voice has unique characteristics. There are two types of dysprosody, linguistic and emotional, that each present with slightly different symptoms. It is possible that one can present with both forms of dysprosody.
