Extended Speech Evaluation of Cleft Palate -Velopharyngeal Dysfunction Affected Children Using Jitter and Nasality Analysis

Manasi R. Dixit; Shaila D. Apte

Communication disorders are very complicated in individuals with cleft lip and/ or palate. In this paper, the pathological cases of speech disabled children affected with cleft type characteristics (CTCs) and Velopharyngeal dysfunction (VPD) are analyzed. The speech signal samples of children of age between three to eight years are considered for the present study. These speech signals are digitized and are used to determine the pathologic speech characteristics. NSI, Jitter Analysis is conducted on speech data samples which are concerned with both place of articulation and manner of articulation. The speech disability of pathological subjects was estimated using results of above analysis.
