Aim. Neurogenic stuttering typically starts after brain injury. In previous research the variation of neurogenic stuttering between different tasks has been contradictory. There is a lack of domestic research on neurogenic stuttering and foreign material is similarly limited. Also, consistent practices between investigations are absent from the literature. The purpose of this study is to provide new information on neurogenic stuttering and other aspects of fluency in patients who have brain injuries.Methods. Five people with a brain injury and diagnosis of neurogenic stuttering after injury took part in this research. The control group consisted of five participants with a brain injury but without neurogenic stuttering. Speech tasks included cartoon narration and spontaneous speech. The data was analyzed by calculating speech and articulation rates, the total amount of pauses, non-fluent pauses, pause durations and pause types most commonly occurring for each task. In addition, quantitative and qualitative characteristics of stuttering were evaluated by calculating percentages and average duration of stuttering and by classifying different types of stuttering. Results and conclusions. The speech and articulation rate were slower in cartoon narration task in comparison to spontaneous speech. The durations of pauses were longer and more non-fluent pauses existed in cartoon narration task than spontaneous speech. In both tasks the most common type was the dysrytmic pause. In cartoon narration task, there was more stuttering whereas in spontaneous speech the durations of stuttering were longer in comparison to cartoon narration task. In this research speech task had influence on the variation of quantitative and qualitative characters of speech fluency on neurogenic stutterers.
