The speech rehabilitation program with speech appliance was evaluated the usefulness. The male subject was a patient of the rehabilitation stage and the female was a patient of the chronic stage.

The score of speech intelligibility test and Nasalance with speech appliance after rehabilitation program was significantly higher than that with other conditions in the male subject. On the other hand, there was no significant difference between the score of speech intelligibility test and Nasalance with obturater and with speech appliance in female subject. These results suggested that the speech rehabilitation program with speech appliance was useful for the patient of the rehabilitation period
