Abstract

The Cleft Lip and Palate (CLP) is a multi-factorial malformation that has genetic and environmental origins. In Colombia, 6 of 10000 children born with this malformation, while in the rest of the world, the proportion is about 1 of each 10000. The CLP originates some kinds of pathologies in the speech such as hypernasality, hyponasality, glottal coup, among others. From all of these pathologies, the hypernasality is the most frequent in CLP patients, appearing approximately, in 90% of the cases. In this work, based on experimental results, a performance analysis of the Teager Energy Operator (TEO) is made in the framework of the hypernasality detection on CLP patients. A generalized version of TEO is applied to validate its discrimination capacity over a dataset containing real voice registers of children with CLP and healthy children. The results showed that TEO has discrimination capacity and can contribute with important information in the hypernasality detection issue.
