This report outlines the revised form of a program developed at the Research Institute of Logopedics and Phoniatrics (University of Tokoyo) for testing students' pronunciation and comprehension abilities, and discusses some refinements which have been made in the general approach. (See AL 002 685 for a description of the basic program.) Under this revised program a record is kept of the number of trials, successes and failures for each word feature considered and of the judgments passed for each word. An analysis of these records is expected to provide information on: (1) the relative difficulties of the word features used, based on the averages obtained from the experimental data, for different students; (2) the comparative difficulty of selected types of word features in certain relations, e.g., initial consonant clusters beginning in "s" and the same clusters without initial "s" (spl vs. pl); (3) the effects of interactions between word features when they are put in sequences of words. The extension of the program to include languages other than English is also discussed. (Author/FWB)
