Normal speech may defect from resonance to disorders. These results from inappropriate coupling of the oral and nasal cavities which frequently occur in cleft palate and operative techniques are used to repair it. Measurement of nasalance score by modern and or exact instrument devices is an important part of the evaluation of patient with resonance disorders due to cleft palate and or velopharyngeal in sufficiency. In this study snap test and phonetic tests after palatoplasty for Persian speaking persons. Paletoplasty was done for 30 people (15 boys and 15 girls) with cleft palate between the age of 5 and 15 years old and had not any problems in hearing and hadn’t cold or any other illness which can affect voice and resonance. Snap test and phonetic test was done for them after surgery. Each of subjects produced prolonged 6 vowels (for three second) 23 consonants in syllable and 69 words (23 in first place.23 in middle place.23 in last place) and electronic system (nasometer) calculated nasalance scores of snap test for vowels and consonants and 69 words productions judging by 5 normal listener and recognizing normal articulation and disarticulation. All of the Persian vowels and consonant in cleft palate persons after palatoplasty are hyper nasal. The most mean nasalance score of vowels is for /i/ and the least mean nasalance score is for /o/ sound. The most mean nasalance score of oral consonant is for /L/ the least mean nasalance score is for /q/ sound. The most of disarticulation includes compensatory the least disarticulation includes substitution in production. The most of compensatory production includes secondary articulation. The most of secondary articulation includes glottalized. The most of obligatory production includes nasalized and omission. The findings are similar to other research’s findings. This study prepared statistical data about nasalance score of Persian sounds in cleft palate person after surgery which can be a good start for repairing surgery in order to improve speech cleft palate. Findings of this study indicates the necessity of completing them with the other studies.
