Speech Recognition for People with Severe Dysarthria

Dysarthria is a common speech disorder which, in its severest form, results in unintelligible speech. This disorder is commonly associated with other general neuromotor disabilities. People with these disabilities may have difficulty in making themselves understood as well as in reliably controlling environmental and communication aids. We propose to apply state-of-the-art Speech Technology research to the recognition of severely dysarthric speech. Off-the-shelf automatic speech recognition (ASR) systems function poorly for these users because of the increased variability of their articulations compared to normal speech and the difficulty of finding suitable corpora for training the recogniser. To overcome these problems we propose to develop a software application which integrates three functions: The speech recognition software application will then be deployed to control electronic assistive technology, either a communication aid or an environmental control system.
