TL;DR: Investigating the temporal characteristics at two levels, duration and variability of syllable durations and the durations of interstress intervals concluded that individuals with ataxic dysarthria and MS showed inflexibility as well as instability of temporal control.
Abstract: 'Scanning speech' has been used as a description of a prominent characteristic of the dysarthria of multiple sclerosis (MS) as well as of ataxic dysarthria in general. It is thought to be measurable as equalized syllable durations. There are seemingly contradictory prosodic-temporal characteristics of ataxic dysarthria: perceptually characterised as prosodic excess as well as phonatory-prosodic insufficiency and acoustic characteristics including signs of isochrony as well as variability. This study investigates the temporal characteristics at two levels, duration and variability of syllable durations and the durations of interstress intervals. A group of 14 individuals with MS and ataxic dysarthria as well as 15 control subjects were studied. It was concluded that individuals with ataxic dysarthria and MS showed (a) for syllables: significantly increased durations and decreased intrautterance variability (more isochrony or syllable equalization) as well as significantly increased interutterance variability; (b) for interstress intervals: significantly increased durations and increased variability (less isochrony). The results point to inflexibility as well as instability of temporal control, which could contribute to the explanation of why the perceptual characteristics are contradictory.

TL;DR: The results of this study suggest that this new intensive treatment may have potential as an effective intervention for nonprogressive dysarthria, however, controlled studies are required to establish treatment efficacy.
Abstract: Purpose This article describes the effects of a new intensive dysarthria treatment program (Be Clear) on speech intelligibility in adults with dysarthria secondary to stroke and traumatic brain inj...

TL;DR: In this article, the authors compared the accuracy and improvement patterns of three speech recognition systems (Microsoft Dictation, Dragon NaturallySpeaking, and VoicePad Platinum) when presented with the speech of a traumatic brain injury survivor with mild dysarthria.
Abstract: People who have dysarthric speech production and other motor disorders that limit their ability to access keyboards may benefit from speech recognition technology. This study compared the accuracy and improvement patterns of three speech recognition systems (Microsoft Dictation, Dragon NaturallySpeaking®, and VoicePad Platinum®) when presented with the speech of a traumatic brain injury survivor with mild dysarthria and a speaker without dysarthria. Data consisted of speech recognition accuracy percentages obtained following each of five training sessions using each system. Accuracy scores were based on participants' reading of preselected sentences and generation of novel sentences. Results showed that, for both speakers, the recognition accuracy of Dragon NaturallySpeaking was significantly better and more consistent than that of the other two systems. The pattern of performance across probes and across systems was consistent between speakers. Given the training procedures employed, all three systems pe...

TL;DR: It is argued that this FAS case should be thought of as a disorder of the feedforward control commands, in particular of the articulator velocity and position maps which are hypothesized to lie along the caudoventral portion of the precentral gyrus.

TL;DR: This study explored the relationship between perception of a high-low vowel contrast and its acoustic correlates in tokens produced by persons with motor speech disorders by using an intelligibility test designed by Kent, Weismer, Kent, and Rosenbek (1989a) and showed that theoustic characteristics of tongue-height errors were not clearly differentiated from the acoustic characteristics of targets.
Abstract: This study was designed to explore the relationship between perception of a high-low vowel contrast and its acoustic correlates in tokens produced by persons with motor speech disorders. An intelli...
