Speech is considered as one of the primary outcome measures of cleft lip and palate management. Speech intelligibility in case of velopharyngeal incompetence depends on the summation of the perceptual subjective degree of hypernasality, glottal articulation, pharyngeal articulation and audible nasal air emission. Objectives: The objective was to correlate between variables related to open nasality and speech intelligibility from anatomical and perceptual point of view to detect which factors have an effect more than others on speech intelligibility. Methods: This study was carried out on 23 children with a mean age of 12.65 year who were suffering from open nasality of speech after repaired cleft palate and did not received any line of speech therapy. Assessment of the patients included both objective and subjective measures Results: By using the logistic mutli-regression analysis, 15 subjective and objective variables were arranged in a numerical order to determine the most effective variable on speech intelligibility. It was shown that the most sensitive predictors (P < 0.005) for speech intelligibility were pharyngealization of fricatives and nasalance scores of oral sentence, while the degree of both open nasality, and palatal mobility were moderate sensitive predictors of speech intelligibility, however all the other remaining parameters were the least sensitive predictors of speech intelligibility. Conclusion: The different parameters used to assess the speech in patients with repaired cleft palate were variably affecting the speech intelligibility. Four certain parameters out of our results were recommended to be highlighted as valid measures of speech outcome in children with hypernasality.
