Tóm tắt

The present study examined aspects of a type of auditory feedback that aims at making interactions with menus more efficient. Specifically, manipulations were made to the auditory counterparts of common computer commands and unrelated words to examine identification performance. By investigating the point at which sped-up versions of text-to-speech, spearcons, can be identified accurately as words, the boundaries at which the efficiency of spearcon use begins to decline can be better defined. Additionally, by examining the effect of category membership on speed and accuracy of spearcon identification, whether an overarching category can facilitate spearcon use can be examined. Results in two experiments demonstrated that spearcon identification began to decline drastically after linear compression leading to 40% of the original audio length. Reaction time data also demonstrated that spearcon efficiency began to decline after the same level of linear compression. Efficiency scores combining reaction time and accuracy also supported the bottom limit of spearcons at 40% of original audio length.
