Hypernasality and Velopharyngeal Impairment

Cleft Palate-Craniofacial Journal, 1994
Although the primary cause of hypernasality is impaired velopharyngeal (VP) function, a variety of other factors influence the outcome perceived by the listener. The purpose of the current study was to assess the relationship between oral-nasal resonance balance and (1) velopharyngeal orifice area; (2) nasal airflow rate; and (3) duration of nasal ...

Hypernasality in singing among children with cleft palate: a preliminary study

International Journal of Oral and Maxillofacial Surgery, 2019
The aim of this study was to document differences in hypernasality during speaking and singing among children with cleft palate and to compare nasality score ratings of trained and untrained listeners. Twenty subjects with cleft palate aged between 7 and

Cross-gender acoustic differences in hypernasal speech and detection of hypernasality

2016 International Workshop on Computational Intelligence (IWCI), 2016
Spectrum of hypernasal speech produced by cleft palate (CP) speakers carries acoustic information regarding hypernasality (HP). This study compares the variation of acoustic features of HP in continuous read speech with gradually increasing severity of HP within and across gender and detect HP.

Analysis of hypernasality by synthesis

Interspeech 2004, 2004
Speakers with velopharyngeal incompetence, produce hypernasal speech across voiced elements. During the production of vowels, due to the defective velopharyngeal mechanism, oral cavity gets coupled with the nasal cavity. This coupling may introduce resonances of nasal cavity in the resulting vowel sound.

Hypernasality in the Presence of “Adequate” Velopharyngeal Closure

Cleft Palate-Craniofacial Journal, 1993
In some instances, hypernasality occurs despite an instrumental assessment of “adequate” velopharyngeal closure. The pressure-flow technique was used to assess the timing characteristics associated with velopharyngeal closure in 11 such subjects. The group's performance was compared to the aerodynamic characteristics of two other subject groups.

Hypernasal Speech following Adenotonsillectomy

Otolaryngology–Head and Neck Surgery, 1981
Extensive study of 120 patients with hypernasal speech following adenotonsillectomy showed that 48 had no evidence of abnormal speech prior to surgery and 41 had minor speech anomalies exacerbated postoperatively. Thirty‐five patients had the classical stigma of submucous cleft palate and another 20 had occult submucous clefts.

Detection of the Parameters of Hypernasality

2009 Sixth International Conference on Information Technology: New Generations, 2009
We analyze several hypernasal speech samples and describe methods to quantify the parameters and properties of hypernasality. This can help medical professionals detect and understand the blurred nasal words that patients try to say. In this way, we may avoid unnecessary medical procedures for hypernasal patients.

Nonlinear Dynamics for Hypernasality Detection

2011
A novel way for characterizing hypernasal voices by means of nonlinear dynamics is presented considering some complexity measures that are mainly based on the analysis of the embedding space. After characterization, feature selection is performed using two strategies, Principal Components Analysis (PCA) and Secuential Floating Feature Selection (SFFS);

Residual hypernasality in repaired cleft palate

Journal of Communication Disorders, 1979
This article reviews selected components of the speech process in children with a repaired cleft palate in order to provide the speech-language pathologist with a framework for decision-making in the selection of appropriate identification and management strategies. Discussion is offered which intends to clarify the phenomena of velopharyngeal valving,
