The book "Analysis of Speech Disorders in Children with Cleft Lip and Palate" offers a comprehensive analysis of speech disorders, particularly hypernasality, in children with cleft lip and palate. It presents an automated, non-invasive approach to measuring hypernasality that facilitates diagnostics during speech therapy. The author, Alexander Reuss, examines various features for detecting hypernasal speech, including articulation features, prosodic features, as well as features based on the Teager energy operator and Mel Frequency Cepstral Coefficients. The detailed description of the extraction process of these features and the classification system in which they are tested is also addressed. Finally, experimental results are presented and discussed, making the book a valuable resource for researchers in the field of pattern recognition.
