TL;DR: The requirement of a structured and organized computerized platform in order to store, organize and make accessible (for selected and protected usage) dysarthric speech corpora and associated patients clinical information is outlined.
Abstract: This paper presents the rationale, objectives and advances of an on-going project (the DesPho-APaDy project funded by the French National Agency of Research) which aims to provide a systematic and quantified description of French dysarthric speech, over a large population of patients and three dysarthria types (related to the parkinson's disease, the Amyotrophic Lateral Sclerosis disease, and a pure cerebellar alteration). The two French corpora of dysarthric patients, from which the speech data have been selected for analysis purposes, are firstly described. Secondly, this paper discusses and outlines the requirement of a structured and organized computerized platform in order to store, organize and make accessible (for selected and protected usage) dysarthric speech corpora and associated patients' clinical information (mostly disseminated in different locations: labs, hospitals, ...). The design of both a computer database and a multi-field query interface is proposed for the clinical context. Finally, advances of the project related to the selection of the population used for the dysarthria analysis, the preprocessing of the speech files, their orthographic transcription and their automatic alignment are also presented.

TL;DR: In this paper, 40 speech-language pathologists listen to randomised recorded samples of the 'Grandfather Passage' read aloud by 10 normal elderly male adults, 10 normal young male adults and 6 dysarthric subjects.
Abstract: Forty speech-language pathologists listened to randomised recorded samples of the ‘Grandfather Passage' read aloud by 10 normal elderly male adults, 10 normal young male adults and 6 dysarthric subjects. The speech samples were rated according to the 38 dimensions devised by Darley and colleagues for the study of the dysarthrias. The ratings of the speech of the older adults fell significantly further from ‘normal' on a seven-point continuum than those given to the young adults on nine of the dimensions. The most apparent young/old differences involved laryngeal dimensions. Ratings for the normal geriatric subjects resembled those of the dysarthric groups in some respects. Several instances of misclassification of the normal elderly individuals as ‘dysarthric' were also observed.

TL;DR: The Whitaker database is a collection of 19 275 isolated‐word utterances spoken by six persons whose speech spans a broad spectrum of dysarthria due to cerebral palsy, available for use in studies of recognition, perception, articulation, and other aspects of speech disorders.
Abstract: The Whitaker database is a collection of 19 275 isolated‐word utterances spoken by six persons whose speech spans a broad spectrum of dysarthria due to cerebral palsy. The database additionally contains utterances by a normal speaker which can be used for reference. The vocabulary is divided into two sets—one of 46 words (the ‘‘TI‐46’’ vocabulary consisting of the alphabet, digits, and 10 control words), the other of of 35 words (the ‘‘Grandfather’’ set consisting of phonetically diverse words). The database is available through the electronic mail network for use in studies of recognition, perception, articulation, and other aspects of speech disorders.

TL;DR: The findings of this study delineate the characteristics of the dysarthria associated with unilateral upper motor neuron lesions and have important implications for identifying potentialupper motor neuron components of other neurogenic disorders of speech and language.
Abstract: Speech motor changes in six patients with focal unilateral upper motor neuron (UUMN) lesions were characterised using a variety of techniques including listener judgements, speech acoustic analyses...

TL;DR: Vocal abnormalities (hoarseness, breathiness, articulatory pattern and inteligibility), as well as perceptive-auditory analysis, showed statistically significant differences between pre and post treatment groups.
Abstract: Mild changes in voice quality and articulation of speech may be seen in early phases of Parkinson´s disease (PD). Voice and speech disturbances in PD constitute a hypocinetic dysarthria or dysarthrophonia and are characterized by monotony and reduced intensity of voice, imprecise articulation and disturbances of rhythm. Favorable results with an intensive method (Lee Silverman Voice Treatment) for the treatment of voice disturbances in PD were recently reported. The main goal of the method is to augment vocal intensity through the increment of phonatory effort. The purpose of the present study was to characterize vocal abnormalities (hoarseness, breathiness, articulatory pattern and inteligibility) in a group of patients with PD and to evaluate the therapeutic efficacy of the Lee Silverman method. Acoustic as well as perceptive-auditory analysis showed statistically significant differences between pre and post treatment groups. Although the articulatory pattern has not considerably changed, the benefits obtained with the improvement in vocal quality positively influenced overall quality of oral communication.
