Intelligibility Rating of L2 Speech Pre- and Postintervention

Abstract

As a result of a recent law passed in Ohio, a program was designed to improve the oral intelligibility of International Teaching Assistants at Bowling Green State University. To evaluate the efficacy of the training, naive undergraduate students were asked to evaluate the pre- and postrecorded speech samples of the international students, both in terms of intelligibility of the sample and the identification of the topic of the monologue. Analysis showed a significant improvement in the intelligibility ratings between pre- and posttraining samples. Further, the average number of correct subject matter identifications was shown to increase, while the average number of incorrect judgments decreased significantly from pre- to posttraining evaluations.
