TL;DR: The results revealed that the CVA subjects presented with features consistent with spastic dysarthria; however, the incidence of the dimensions identified was lower and the severity less than previously reported in the literature.
Abstract: The perceptual speech characteristics of a group of 20 subjects with persistent dysarthria following Upper motor neurone (UMN) damage resulting from cerebrovascular accident (CVA) were compared with those of a normal non-neurologically impaired control group matched for age and sex. The perceptual assessments included an inventory of 32 perceptual speech dimensions, the Frenchay Dysarthria Assessment (FDA), and the Assessment of the Intelligibility of Dysarthric Speech (ASSIDS). The results revealed that the CVA subjects presented with features consistent with spastic dysarthria; however, the incidence of the dimensions identified was lower and the severity less than previously reported in the literature. Comparison between the CVA and the control groups revealed reduced speech intelligibility in the CVA group and deficits in all aspects of speech production including respiration, phonation, resonance, and prosody. The perceptual profile obtained from the assessments is interpreted with reference to the i...

TL;DR: Findings suggest that speech movements of the tongue are differentially more impaired than those of the lower lip in PwDMS, which may explain, in part, their slowed speech rate.
Abstract: Background Multiple sclerosis can affect the speech motor system and result in dysarthria. Objectives This pilot study sought to identify tongue, lip, and jaw motor deficits in persons with dysarthria due to multiple sclerosis (PwDMS) to better understand the speech motor mechanisms that underlie their aberrant speech. Methods Tongue and jaw movements during “ai” and lower lip and jaw movements during “bob”were examined in eleven PwDMS and fourteen age- and sex-matched controls using three-dimensional electromagnetic articulography. Movement duration, maximum displacement, peak speed, stiffness (i.e., peak speed/displacement ratio), and jaw contribution to lower lip and tongue displacements were of particular interest. Results Whereas most kinematic measures yielded significant between-group differences for tongue and jaw motor performance during “ai”, lower lip and jaw motor performance during “bob” were mostly comparable between groups. Conclusion Findings suggest that speech movements of the tongue are differentially more impaired than those of the lower lip in PwDMS. Particularly the ability to move the tongue with adequate speed during speech was significantly impaired in PwDMS, which may explain, in part, their slowed speech rate. Aberrant jaw kinematics during “ai” may be a compensatory strategy to maximize speech clarity in the presence of the impaired tongue motor performance.

TL;DR: General figures based on syllable-level annotation mining are presented, including detailed information about healthy/pathological speakers variability, and the results of automatic timing parsing of interval sequences in speech syllable annotations performed using TGA (Time Group Analysis) methodology are reported.
Abstract: A comparison of how healthy and dysarthric pathological speakers adapt their production is a way to better understand the processes and constraints that interact during speech production in general. The present study focuses on spontaneous speech obtained with varying recording scenarios from five different groups of speakers. Patients suffering from motor speech disorder (dysarthria) affecting speech production are compared to healthy speakers. Three types of dysarthria have been explored: Parkinson's Disease, Amyotrophic Lateral Sclerosis and Cerebellar ataxia. This paper first presents general figures based on syllable-level annotation mining, including detailed information about healthy/pathological speakers variability. Then, we report on the results of automatic timing parsing of interval sequences in speech syllable annotations performed using TGA (Time Group Analysis) methodology. We observed that mean syllable-based speaking rates in time groups for the healthy speakers were higher than those measured in the recordings of dysarthric speakers. The variability in timing patterns (duration regression slopes, intercepts, and nPVI) depended also on the speaking styles in particular populations.

TL;DR: This study explored the incidence of primitive cranio-oropharyngeal motor patterns and their relationship to age in cerebral palsied individuals.
Abstract: Fifty-one cerebral palsied individuals were tested for a complex of primitive cranio-oropharyngeal motor patterns. This study explored the incidence of these patterns and their relationship to age,...

TL;DR: それに基づいて, Broca野 (左下前頭回三角部・弁蓋部) 周辺の限局梗塞 病変で言語症状を呈した
Abstract: 構音障害の定義・分類を神経学の立場から提示した.それに基づいて, Broca野 (左下前頭回三角部・弁蓋部) 周辺の限局梗塞病変で言語症状を呈した8症例の症候と病巣 (X線CT・MRI) とを対比した. (1) 8症例全例で, 病変による程度の差はあるものの構音の障害が認められた. (2) 8症例の構音の障害の性質は多様で, 病変部位との対応関係は明確でなかった. (3) Broca野の後に接する左中心前回下部に主病巣を持つ症例で, 構音の障害が特に著明であり, 主症状として持続した. (4) 病変が左中心前回下部から前方のBroca野に進展する症例では, 持続性失語症状がみられた.
