Second Formant Transition Characteristics in Persian-Speaking People With Broca’s Aphasia

Background and Objectives: This study aims to examine the acoustic characteristics of the second formant (F2) transition produced by Persian-speaking Broca’s aphasics compared to normal speakers. Methods: Eight subjects diagnosed with Broca’s aphasia and eight normal speakers participated in this study. The subjects produced six words (/ bâd / - / pâ / - / tâb / - / dâs / - / kâr / and / gâz /). The samples were analyzed using PRAAT and the F2 transition was measured for these words. F2 values were compared to the data available in the literature. Results: Since the data distribution was abnormal in this study, the Mann-Whitney U test was applied. The results of this study show that the mean of the second formant transition in healthy people and people with aphasia are significantly different from each other in the words /Bâd/ and /Kâr/ (P
