Perceptual and Acoustic Predictors of Intelligibility and Acceptability in Cantonese Speakers with Dysarthria.

Perceptual and Acoustic Predictors of Intelligibility and Acceptability in Cantonese Speakers with Dysarthria.

The primary aim of this study was to determine contributing factors to listener judgments of acceptability, a global measure of severity, in speakers with dysarthria. Participants included 33 Cantonese speakers with dysarthria, ages 14-78 years, with mixed etiology (including Parkinson disease, cerebral palsy, and cerebrovascular accident [CVA]. Listeners were 12 speech and hearing sciences students. […]

Reliability of Speech Intelligibility Ratings Using the Unified Huntington Disease Rating Scale.

Reliability of Speech Intelligibility Ratings Using the Unified Huntington Disease Rating Scale.

The Unified Huntington Disease Rating Scale (UHDRS) is widely used by medical, nursing, and allied-health professionals in the management and study of patients with Huntington disease (HD), who sometimes present with decreased speech intelligibility. As such, examining the reliability of speech intelligibility ratings using the UHDRS is critical in evaluating its utility as an instrument […]

Impact of Pallidotomy on Physiological Articulation Function and Speech Intelligibility in Parkinson Disease.

Impact of Pallidotomy on Physiological Articulation Function and Speech Intelligibility in Parkinson Disease.

The objective of this study was to evaluate the effects of posteroventral pallidotomy on perceptual and physiological measures of articulatory function and speech intelligibility in Parkinson disease (PD). The study examined 11 participants with PD who under-went posteroventral pallidotomy. Physiological measures of lip and tongue function and perceptual measures of speech intelligibility were obtained prepallidotomy […]

Reliability of Speech Intelligibility Ratings Using the Unified Parkinson Disease Rating Scale.

Reliability of Speech Intelligibility Ratings Using the Unified Parkinson Disease Rating Scale.

The Unified Parkinson Disease Rating Scale (UPDRS) is widely used by medical, nursing, and allied-health professionals in the management and study of patients with Parkinson disease (PD), who sometimes present with decreased speech intelligibility. As such, examining the reliability of speech intelligibility ratings using the UPDRS is critical in evaluating its utility as an instrument […]

Computer Speech Recognition As an Objective Measure of Intelligibility.

Computer Speech Recognition As an Objective Measure of Intelligibility.

The effectiveness of computer speech recognition as an objective measure of intelligibility was explored. A commercially available program was assessed following the manufacturer’s protocol to analyze speech samples from three speakers without neurogenic speech disorders, one speaker with moderate spastic dysarthria, and a synthesized speech sample. The system identified the synthesized speech most accurately, and […]

Influence of Stimulus Sentence Characteristics on Speech Intelligibility Scores in Hypokinetic Dysarthria (Report)

Influence of Stimulus Sentence Characteristics on Speech Intelligibility Scores in Hypokinetic Dysarthria (Report)

This study was designed to investigate the effects of signal independent sentence characteristics on speech intelligibility scores. Six adult speakers with untreated hypokinetic dysarthria were audio recorded while orally reading randomly selected sentences from the Sentence Intelligibility Test (SIT). These audio recordings were then utilized in a transcription task to obtain speech intelligibility scores. The […]

Tongue Strength and Speech Intelligibility in Oculopharyngeal Muscular Dystrophy.

Tongue Strength and Speech Intelligibility in Oculopharyngeal Muscular Dystrophy.

Tongue weakness is presumed to contribute to reduced articulatory precision and speech intelligibility, but studies of dysarthric speakers do not consistently find a correlation between decreases in maximal tongue strength and speech measures. In this study, estimates of maximal tongue strength and tongue pressure during the syllable [TEXT NOT REPRODUCIBLE IN ASCII] were obtained from […]
