spastic dysarthria: characteristics
- strain-strangle, harsh voice
- hypernasality
- problems with executing movement
spastic dysarthria: type of disease
pseudobulbar palsy
flaccid dysarthria: characteristics
- breathy voice
- problems with executing movement
- monopitch
- caused by weakness
flaccid dysarthria: type of disease
bulbar palsy
ataxic dysarthria: characteristics
