Objectives: This study conducts a comparative analysis of the temporal facets of velopharyngeal coarticulation in Persian-speaking adults, differentiating between subjects with and without cleft palate, across three distinct vowel contexts. Methods: The study included 14 adults who had undergone cleft palate repair, with or without cleft lip and presented moderate to severe hypernasality. Another 14 adults without cleft palate were included in the study. The age range of participants was 18 to 50 years. By utilizing the Praat software, version 6.1.50, the study obtained data for the four temporal parameters by analyzing acoustic waveforms and spectrograms within three distinct vowel contexts. The analysis included the calculation of ratios of nasalization duration to neutralize the influence of speech rate variations between the cleft palate and control groups. Results: The results revealed that adults with cleft palate exhibited significantly extended durations for the four temporal parameters compared to the control group (P
