Table 12: Evaluation metrics for all severity groups when using an RF classifier. appropriate therapy. Future studies should compare results when using prosody-based features in other forms of dysarthria such as Parkinsonian dysarthria to provide stronger generalization. A cross-database analysis to confirm our findings with other datasets will also be required to further support the benefits of prosody for dysarthria severity assessment. Lastly, a follow-up study on how prosody-based features can be used for diagnosis would be important to help speech therapists determine what specific aspects of prosody are impaired in an individual with dysarthria.
