Hypernasality following adenoid removal
Irish Journal of Medical Science, 1994Persistent hypernasality after adenotonsillectomy is not an uncommon complication, occurring in approximately 1 in 1,500 procedures. The primary aetiological factor is an underlying congenital abnormality of the palate which is unmasked by removing the adenoidal tissue.

Acoustic Speech Analysis for Hypernasality Detection in Children
2006 International Conference of the IEEE Engineering in Medicine and Biology Society, 2006Here, an analysis of different acoustic features and their influence in automatic identification of hypernasality is shown. Effective feature selection method includes preprocessing of the initial feature space based on statistical independence analysis.

Automatic Detection of Hypernasality in Children
2011Automatic hypernasality detection in children with Cleft Lip and Palate is made considering five Spanish vowels. Characterization is performed by means of some acoustic and noise features, building a representation space with high dimensionality. Most relevant features are selected using Principal Components Analisis and linear correlation in order to ...

The Effect of Articulatory Adjustment on Reducing Hypernasality
Journal of Speech, Language, and Hearing Research, 2012Purpose With the goal of using articulatory adjustments to reduce hypernasality, this study utilized an articulatory synthesis model (Childers, 2000) to simulate the adjustment of articulatory configurations with an open velopharynx to achieve the same acoustic goal as normal speech simulated with a closed velopharynx.

Spectral Properties and Quantitative Evaluation of Hypernasality in Vowels
Cleft Palate-Craniofacial Journal, 1996A new technique for evaluating hypernasality using an acoustic approach is presented. In a preliminary study using this technique, nasal resonance was assessed in 17 normal subjects and 16 subjects judged to be hypernasal. Analyses of the one-third-octave power spectra revealed an increase in power level between the first and second formant, and a ...

The Modification of Hypernasality in Young Children
Language, Speech, and Hearing Services in Schools, 1984This paper presents an approach to voice therapy programming for young children who are hypernasal. Some general principles underlying the approach are presented and discussed.

Spectral analysis of hypernasality
2010The aim of this study was to further investigate one-third-octave analysis by (a) extending the application of the analysis to three vowels, /inverted a sign/, /inverted c sign/ and /u/, in addition to /i/ which has been investigated previously, and by (b) comparing the spectra of each vowel produced in oral and nasal consonant contexts for each ...

Adenoid Involution and Developing Hypernasality in Cleft Palate
Journal of Speech and Hearing Disorders, 1980Information about the adenoid mass is reviewed, and the phenomenon of gradual development of hypernasality as a result of adenoidal involution is described in two patients selected from a sample of 122 with repaired cleft palate. Three types of radiographically determined closure patterns of the velum against the adenoid pad are presented. Our clinical

Hypernasality Detection Using Zero Time Windowing
2018 International Conference on Signal Processing and Communications (SPCOM), 2018The hypernasality in cleft palate speech is characterized by the presence of nasal peak in the vicinity of first formant of vowel spectrum. A high spectral resolution technique, which can resolve these two peaks, is desirable for the automatic detection of hypernasality.
