Acoustic transformations to improve the intelligibility of dysarthric speech
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...
متن کاملIntelligibility of modifications to dysarthric speech
Dysarthria is a motor speech impairment affecting millions of people. Dysarthric speech can he far less intelligible than that of non-dysarthric speakers, causing significant communication difficulties. The goal of this work is to understand the effect that certain modifications have on the intelligibility of dysarthric speech. These modifications are designed to identify aspects of the speech ...
متن کاملInfluence of visual information on the intelligibility of dysarthric speech.
PURPOSE To examine the influence of visual information on speech intelligibility for a group of speakers with dysarthria associated with Parkinson's disease. METHOD Eight speakers with Parkinson's disease and dysarthria were recorded while they read sentences. Speakers performed a concurrent manual task to facilitate typical speech production. Twenty listeners (10 experienced and 10 inexperie...
متن کاملAssessment of dysarthric speech through rhythm metrics
niversity ci.2012.0 Abstract This paper reports the results of acoustic investigation based on rhythmic classifications of speech from durationmeasurements carried out to distinguish dysarthric speech from healthy speech. The Nemours database of American dysarthric speakers is used throughout experiments conducted for this study. The speakers are eleven young adult males with dysarthria caused ...
متن کاملImproving the intelligibility of dysarthric speech
Dysarthria is a speech motor disorder usually resulting in a substantive decrease in speech intelligibility by the general population. In this study, we have significantly improved the intelligibility of dysarthric vowels of one speaker from 48% to 54%, as evaluated by a vowel identification task using 64 CVC stimuli judged by 24 listeners. Improvement was obtained by transforming the vowels of...
