Dichotic and diotic presentation of speeded speech.

A study was done to determine the utility of recovering the discarded segments which are a necessary product of speech time compression using the method of Fairbanks. In this study the discarded segments were saved, and the speech signal processed digitally in such a way that the discarded segments could be played for one ear while the remaining segments were presented to the other ear. It was found that this manner of dichotic presentation was more intelligible than the customary manner of diotic presentation for several compression ratios and discard intervals.
