The various interventions for dysarthria that have been reported are introduced and their effectiveness is summarized. Nonspeech exercise has been performed as training for velopharyngeal closure insufficiency, but no evidence exists that it improves speech performance. Since voice volume, posture, and the selected speech tasks and sounds are thought to affect velopharyngeal closure, further research is necessary for understanding the effectiveness of the training. The training efficacy of nonspeech oral motor exercise on speech is meager; therefore, it is necessary to carefully consider patient selection suitable for this training. With articulation training, it is desirable to practice with consideration of the order and difficulty of speech tasks based on the motor learning theory. Control of speaking rate and setting of the training environment are also important for improving the patient's daily communication. In the future, it will be necessary to study the training effects of approaches that have not been verified.
