Spectral moment analysis (SMA) was used to describe voiceless alveolar and velar stop-plosive production in Persian-speaking children with repaired cleft lip and palate (CLP). Participants included 11 children with bilateral CLP who were undergoing maxillary expansion and 20 children without any type of orofacial clefts. Four of the children with CLP also exhibited backed (palatal) placement for alveolar stops. All children produced consonant-vowel-consonant nonsense words that targeted the plosives /t/ and /k/. SMA revealed that children with CLP had significantly reduced first spectral moment of /t/ and /t/-/k/ difference. Children with CLP who produced palatal stops for alveolar targets also had lower but non-significant first spectral moments for /t/ as compared with children with CLP who did not produce palatal stops. The results are consistent with previously reported findings for English-speaking children with repaired CLP and further suggest that maxillary arch constriction may be a contributing factor for (a) reduced spectral distinction of alveolar targets and/or (b) palatal substitutions for alveolar targets.
