This paper describes modifications to acoustic speech signals produced by speakers with dysarthria in order to make those utterances more intelligible to typical listeners. These modifications include the correction of tempo, the adjustment of formant frequencies in sonorants, the removal of aberrant voicing, the deletion of phoneme insertion errors, and the replacement of erroneously dropped p...

A 62-year-old woman presented with 1 year of slowly progressive dysarthria, difficulty chewing food, sialorrhea, dysphagia, and unintentional 20-pound weight loss. Neurologic examination demonstrated moderate dysarthria, marked tongue weakness with atrophy and fasciculations, multifocal muscular atrophy, and diffuse hyperreflexia, including a jaw jerk. EMG showed diffuse fibrillation potentials...

The reported study investigated the effect of 7 rate control methods (RCM) on running speech intelligibility, speaking rate (SR), articulation rate (AR) and pause characteristics in 27 individuals with dysarthria. The data reveal that with the exception of slower on demand, each RCM resulted in lower mean SRs and ARs (p < 0.05). Clinically significant improvements in intelligibility were found ...

Speech signal analysis is a powerful tool that facilitates the monitoring and tracking of symptom deterioration caused by neurodegenerative disorders, typically achieved using either sustained vowels, diadochokinetic exercises or running speech. This study expands our previous work on movement produced jaw-tongue biomechanical system. The aim to further investigate effects neuromotor activity d...
