Hypernasality in dysarthric speakers following severe closed head injury: a perceptual and instrumental analysis

Abstract: Hypernasality in the dysarthric speech of 20 severely closed-head- injured (CHI) subjects was investigated using both perceptual and instrumental techniques. A perceptual analysis of the speech of the CHI subjects was performed using a four-point rating scale for hypernasality. Instrumental assessment was carried out using a computerized accelerometric technique yielding a nasal coupling index. Results revealed a high incidence of perceived hypernasality (95%) in the speech of subjects in the CHI group. More than half of these subjects exhibited hypernasality of speech to a moderate to severe degree. When compared with a control group matched for age and sex the severely CHI subjects were perceived as being significantly more hypernasal. Instrumental assessment revealed that the functioning of the velopharyngeal valve in the group of CHI subjects was significantly impaired compared to the control group. The study highlighted the need to evaluate the perceptual and instrumental assessment results for the s...

Speech and language in a genotyped cohort of individuals with Kabuki syndrome.

Abstract: Speech and language deficits are commonly associated with Kabuki syndrome. Yet little is known regarding the specific symptomatology of these disorders, preventing use of targeted treatment programs. Here we detail speech and language in 16 individuals with Kabuki syndrome (thirteen with KMT2D mutations, one with a KDM6A mutation, and two mutation-negative cases), aged 4-21 years. The most striking speech deficit was dysarthria, characterised by imprecise consonants, harsh vocal quality, hypernasality, reduced rate and stress, and distorted pitch. Oromotor functioning was also impaired. Delayed, rather than disordered, articulation and phonology was common. Both receptive and expressive language abilities were reduced in the majority and deficits were noted across all language sub-domains (i.e., semantics, syntax, morphology, and pragmatics) with no clear differentiation or specific language profile. Individuals with Kabuki syndrome present with a heterogenous pattern of oromotor, speech, and language deficits. This variability fits with the multisystem nature of the disorder, which may encompass neurological, orofacial structural, hearing, and cognitive deficits, any or all of which may contribute to speech or language impairment. Our results suggest that all individuals with Kabuki syndrome have some level of communication deficit, warranting speech pathology involvement in all cases.

Speech and oral motor learning in individuals with cerebellar atrophy.

Abstract: The purpose of this study was to determine whether cerebellar pathology interferes with motor learning for either speech or novel tasks. Practice effects were contrasted between persons with cerebe...

Changes in speech production associated with alphabet supplementation.

Abstract: Purpose This study examined the effect of alphabet supplementation (AS) on temporal and spectral features of speech production in individuals with cerebral palsy and dysarthria. Method Twelve speak...

An acoustical study of the fricative /s/ in the speech of individuals with dysarthria.

Abstract: This paper reports on measurements of several acoustic attributes of the fricative consonant /s/ produced in word-initial position by normally speaking adults and by speakers with neuromotor dysfun...
