- Abstract
Objective: Voice onset time (VOT) may be affected by deficits in laryngeal or supralaryngeal structures. This study aimed to compare the VOT parameters between the children with repaired cleft lip and/or palate (CL/P) and their healthy peers. Material and Methods: Thirty-nine children with repaired CL/P (X̅±SD age; 11.51±3.53 years) and 39 healthy children (X̅±SD age; 11.44±3.40 years) were included in the study. Clinical data including age, gender, speaking language, hearing status, type of CL/P, presence of lip/palate repairment, results of speech-sound disorder examination, and presence of malocclusion and/or oronasal fistula were retrospectively collected. VOT values for/pa/,/ta/, and/ka/syllables were obtained using Praat software and compared between the study group (SG) and the control group (CG). Results: VOT values differed significantly between the (SG) and (CG) which were prolonged in the SG for all measured/pa/(p=0.015),/ta/(p=0.045), and/ka/(p=0.037) syllables. In the SG, the longest VOT was observed for the/ka/,/ta/, and pa/syllables, respectively. Conclusion: The presence of CL/P may have contributed to prolonged VOT values in Turkish-speaking children. Since VOT is a reliable acoustic parameter closely interacting with speech structures, clinicians should be aware of this phenomenon.
