Standardization of Speech Materials for Underwater Research 1: Comparative Intelligibility of Monosyllabic Word Lists

摘要

Two experiments are reported in which the underwater intelligibility scores of four standard word lists were compared. As would be expected, closed-set word lists produced higher scores than did open-ended tests. Alternate forms of two tests were compared and the results indicated that lists which are 'equated for difficulty' in normal environments also are reasonably equated underwater. A preliminary analysis of phoneme type distortion was derived from one closed-set test. The results appeared to demonstrate that, for this type of experiment, the most common phoneme error was in place of production and that fricatives were most affected. (Author)
