OBJECTIVE The aim of this study was to compare the speech performance of fluent speakers and individuals who stutter during spontaneous speech, automatic speech, and singing. METHODS The study sample was composed of 34 adults, 17 individuals who stutter and 17 fluent controls, matched for gender and age. The speech performance of participants was compared by means of three tasks: monologue, automatic speech, and singing. The following aspects were assessed: total number of common disruptions and total number of stuttering-like disruptions. RESULTS Statistically significant difference was observed only for the monologue task in both intra- and inter-group comparisons. CONCLUSIONS The outcomes of this study indicate that tasks of higher motor and melodic complexities, such as the monologue task, negatively affect the speech fluency of both fluent speakers and individuals who stutter.

D013342 Stuttering A disturbance in the normal fluency and time patterning of speech that is inappropriate for the individual's age. This disturbance is characterized by frequent repetitions or prolongations of sounds or syllables. Various other types of speech dysfluencies may also be involved including interjections, broken words, audible or silent blocking, circumlocutions, words produced with an excess of physical tension, and monosyllabic whole word repetitions. Stuttering may occur as a developmental condition in childhood or as an acquired disorder which may be associated with BRAIN INFARCTIONS and other BRAIN DISEASES.
