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 …

Adapting Large-Scale Speaker-Independent Automatic Speech Recognition to Dysarthric Speech
… improvements in speaker-independent automatic speech recognition (ASR), the performance of large-scale speech recognition systems is still significantly worse on dysarthric speech than on standard speech. Both the inherent noise of dysarthric speech and the lack of large datasets add to the …

Acoustic-based assistive technology tools for dysarthria managment
… 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 diadochokinetic (DDK) analysis and …

Confusion modelling for lip-reading
… of this process, with the aim of building a speech recognition system entirely driven by lip movements. However, this work has so far produced poor results because of factors such as high variability of speaker features, diffi�culties in mapping from visual features to speech sounds, and high …

Acoustic features of impaired articulation due to amyotrophic lateral sclerosis
… amyotrophic lateral sclerosis (ALS) leads to speech impairment. Despite the devastating consequences of speech impairment to life quality, few options are available to objectively assess speech motor involvement. The overarching goal of this research was to derive objective measures of speech …

Voice onset time variation in stop consonant to vowel transitions
… are goals of reducing the motor complexity of speech 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 …
