Dysarthria is defined as a locomotor disorder of the vocal speech organ due to a pathological change of nerve and muscle systems. Several methods of speaking rate control have been widely used for the rehabilitation of dysarthria. However, these methods are not always effective depending on the condition of the dysarthric patient. In this study, we investigated the performance of tempo perception of dysarthrias, which has not yet been fully studied. Several types of experiments were conducted for both dysarthric patients and normal subjects. The experiments included speech production and tapping tasks with and without reference samples of utterances or tapping.

The experimental results showed that some of the dysarthric subjects exhibited disorders both in the locomotor of the vocal speech organ and in their memory of tempo and rhythm.
