Speech that exhibits deviations in continuity, fluidity, ease of rate and effort, with hesitations or repetition of sounds, words, or phrases; lack of skillfulness in speech. Disfluency is normal in pre-school language development. In later years, it can be due to congenital conditions such as Down’s syndrome, or acquired—either early, as in stuttering, or late, as may occur in Parkinson’s disease.

However, even when the treatment is not targeted to voice issues, it can be noted that the breathing pattern, when regarded as predominantly oral, determines an increased effort of the vocal emission of the child, a fact which may cause an overload in the larynx and may also contribute for the presence of a vocal disorder [14].
