A procedure for detecting and displaying a measure of the acoustic coupling through the velopharyngeal port during speech was developed. The procedure was used with nine deaf students to train for velar control in both unsupervised and tutorial drills. Results showed that tutoring with the display resulted in acquisition of new speech skills, including ability to produce vowels in isolation, in words, and in phrases with proper control of the velum. Objective evaluations demonstrated that eight of the nine students showed various amounts of improvement. (SK)
