Acoustic-based assistive technology tools for dysarthria managment
… algorithms in the detection and treatment of dysarthria, a neurological motor speech disorder. The novel algorithms presented in this thesis include a silence, unvoiced and voiced segmentation technique for dysarthric speech based on linear prediction error variance (LPEV), an automatic …

Treatment of Ataxic Dysarthria Using a Modified Be Clear Approach: A Pilot Study
Ataxic dysarthria is a motor speech disorder characterized by irregular articulatory errors as well as changes to prosody, such as atypical variability in loudness, pitch and stress (Duffy, 2020). Like many other motor speech disorders, ataxic dysarthria can impact an individual's quality of life, …

The Incidence, Co-occurrence, and Predictors of Dysphagia, Dysarthria, and Aphasia after Acute Ischemic Stroke
Background- Dysphagia, dysarthria and aphasia are frequent sequelae of stroke. We sought to identify their frequency, co-occurrence, and predictors of them after acute ischemic stroke. Methods- First, we used the Registry of the Canadian Stroke Network’s (RCSN) database (2003–2008) from one stroke …

Factors influencing the efficacy of delayed auditory feedback in treating dysarthria associated with Parkinson's disease
… males with Parkinson's disease and an associated dysarthria participated in the study. Results revealed that for all three speakers, DAF significantly reduced reading rate and produced significant improvements in either intelligibility (for Speaker 3) or fluency (for Speakers 1 and 2). A delay …

The application of linear and nonlinear estimators of acoustic variability in the assessment of speech motor control in hypokinetic dysarthria
… estimators' ability to differentiate hypokinetic dysarthria from unimpaired speech, as well as speech of young adults from older adults. In addition, the variability results of hypokinetic dysarthric speakers were compared with the results of standard diagnostic assessments.;Twenty-three speakers …

Voice onset time variation in stop consonant to vowel transitions
… for individuals with cerebral palsy having dysarthria. In this study, measurement and analysis were made to compare an individual with spastic Cerebral Palsy (CP) having dysarthria to an individual with athetoid CP having dysarthria as well as to a non-dysarthric individual. Each …

Optimization of acoustic feature extraction from dysarthric speech
Dysarthria is a motor speech disorder characterized by weak or uncoordinated movements of the speech musculature. While unfamiliar listeners struggle to understand speakers with severe dysarthria, familiar listeners are often able to comprehend with high accuracy. This observation implies that …

Social Aspects of Communication in Parkinson's Disease
… consequences of the speech impairment (dysarthria). Accounts of people with dysarthria have shown that its impact on quality of social participation can be varied and profound. However, level of participation has not been investigated. Reduction in social activity and social networks has …

Articulatory motor performance as a function of phonetic complexity in Parkinson's disease
… deficits in talkers with progressive dysarthria due to Parkinson's disease (PD). Methods: Articulatory kinematics were recorded using 3D electromagnetic articulography from 15 talkers with PD (58-84 years) and 15 healthy controls (55-80 years) while they produced target words embedded …

Impact of speech amplification devices on quality of life in persons living with Parkinson's disease and hypophonia : a quality improvement project
… speech disorder of PD is known as hypokinetic dysarthria, occurring in various stages in up to 90% of Persons Living with Parkinson's Disease (PLwPD) (Mohseni et al., 2023). Hypophonia, or reduced speech intensity, is the most prevalent symptom of hypokinetic dysarthria that develops in about …
