Information Processing Models and Computer Aids for Human Performance. Task 1. Second-Language Learning

Abstract

Two experiments testing the effectiveness of the Automated Pronunciation Instructor (API) were carried out with Spanish-speaking students attempting to learn English. Experiment I tested the computer-generated display of the student's tongue position during stressed vowels. New experimental procedures for evaluating the extent of pronunciation changes were developed and applied. Experiment II tested the effectiveness of the additional two displays. Highly significant training effects were obtained for all three displays, despite the presence of variability in the data. The report concludes with a general discussion of proposed changes to future versions of the API system.
