Dysarthria refers to motor neuron speech disorders that
limit the ability to control muscle groups used for speech
production. Dysarthric speech has reduced intelligibility
due to being slurry, breathy and slow compared to
typical speech. The modern advancements of automatic
speech recognition (ASR) and the increase of speechcontrolled systems raise the question on their
inclusiveness for speakers with dysarthria.

This study evaluated the performance of two popular
commercial ASR systems with dysarthric speech and
compared the performance with state-of-the-art
dysarthric speech ASR systems.
