Methods: In this cross-sectional and comparative study, nasalance was measured in the speech of 112 children (55 boys and 57 girls) in Tehran, Iran. After auditory screening and speech assessments, the subjects who get the sufficient criterions entered the study. Speech sample was obtained by imitation and repeating sentences (14 oral and 3 nasal sentences) and mean nasalance score was measured by Nasal view software.

Results: A mean nasalance score of 46.25% was obtained for nasal sentences and a mean score of 43.67% for fricative sentences, 43.41% for affricative sentences and 42.21% for stop sentences. There was higher nasalance scores in girls but the difference was not significant (p=0.201) there was a significant difference in nasalance scores between different age groups in stop (p=0.037), fricative (p=0.036) and nasal sentences (p=0.032).

Conclusion: Findings of this study prepared good statistical data about nasalance scores in normal Persian-speaking children aged 3.5-6.5 years.
