The initial results of investigations into the use of current commercial automatic speech recognition (ASR) software by people with speech disability (dysarthria) is presented, together with a brief summary of the history of the development of ASR and its applications for the disabled. Results confirm the viability of dysarthric use, identify areas of further investigation for improved recognit...

BACKGROUND People with acquired progressive dysarthria typically experience increased problems with intelligibility in everyday conversation as their disease progresses. Such problems are likely to impact on both the person with dysarthria and those with whom they interact. If this is the case then we may ask questions not just about the nature of these problems but how it is that such problems...

Leptospirosis can present with severe cases such as polymyositis, peripheral neuropathy, and rarely, Guillain-Barré Syndrome (GBS). This paper reports a case who presented dysarthria GBS. A female patient complaints of weakness, dizziness, diarrhea, dysarthric. Her assessments included muscle strength globally 4/5 deep tendon reflexes hypoactive. An electromyographic examination was performed t...

Dysarthria is a motor speech disorder that impairs the physical production of speech. Modern automatic speech recognition for normal speech is ineffective for dysarthric speech due to the large mismatch of acoustic characteristics. In this paper, a new speaker adaptation scheme is proposed to reduce the mismatch. First, a speaker with dysarthria is classified into one of the pre-defined severit...

The advent of MRI technique has enabled the diagnosis of neuronal migration disorders(NMD) and made it possible to make "in vivo" diagnosis. Congenital bilateral perisylvian syndrome(CBPS) is a recently described disease identify characterized by pseudobulbar palsy, epilepsy, mental retardation, and migration disorders in the bilateral perisylvian area. We have identified four CBPS patients bas...

This study examined listeners' endorsement of cognitive, linguistic, segmental, and suprasegmental strategies employed when listening to speakers with dysarthria. The study also examined whether strategy endorsement differed between listeners who earned the highest and lowest intelligibility scores. Speakers were eight individuals with dysarthria and cerebral palsy. Listeners were 80 individual...

Nine patients with pure dysarthria underwent computed tomography or magnetic resonance imaging. Eight patients had infarcts of lacunar or larger size in the internal capsule: four in the superior portion of the anterior limb or adjacent corona radiata and four in the superior portion of the genu or the adjacent corona radiata. In one patient, there was a small infarct in the bulbar motor cortex...

This work is focused on the design and evaluation of a suboptimal classifier for dysarthria assessment. The classification relied on self organizing maps to discriminate 8 types of dysarthria and a normal group. The classification technique provided an excellent accuracy for assessment and enabled clinicians with a powerful relevance analysis of the input features. This technique also allows a ...

Central pontine myelinolysis (CPM) and extrapontine myelinolysis (EPM) are well-recognized syndromes that are related to various conditions such as rapid correction of hyponatremia and chronic alcoholism. We report a very case of a patient with dysarthria, dysphagia and psychiatric symptoms including abnormal behavior starting after alcohol withdrawal, with radiological evidence of CPM and EPM....

The articulatory function of the labial musculature has been investigated electromyographically before and after treatment with l-dopa in patients with Parkinsonism who had dysarthria. Before medication the EMG traces generally showed a constant, abnormally increased, tonic activity, together with disturbed reciprocal innervation, which impaired the articulatory activity. After medication the t...
