Improvement in intelligibility and in general merit of speaking was demonstrated among 88 speakers of 4 groups who used the Self-Administered Intelligibility Testing-Training Unit programmed with multiple-choice intelligibility test material. These findings were demonstrated by the higher intelligibility scores and merit ratings for words spoken late in a one-hour instructional session relative to ones spoken early. The intelligibility and merit scores were assigned by panels of listeners representing three racial groups.
