The practicality of using speeded speech as an educational medium was explored in an Immersion study, in a Criterion study, and in Retention studies. Tapes of novels were used for listening; compression was achieved by a device that removed small segments of the tape-recorded speech sounds and, then, abutted the remainder of the speech record together. In the Immersion study, seven male college students listened to high spped speech (425 wpm-475 wpm) for five days, 11 hours a day. The results of this experiment confirmed previous findings that comprehension of time-compressed speech can be improved by simple practice routines to relatively high levels at speeds of about 2-1/2 times normal speed. In the Criterion study, seven of 10 male college students reached criterion, or 90 percent of normal speed score at least once on a listening test presented at 375 wpm. However, they did not reach criterion consistently. The Retention studies were designed to determine to what extent the skill of listening to compressed speech is retained, and to what extent material learned via compressed speech is retained. The results indicated that content is retained, but that this may or may not be true of skill. Further research is anticipated. (MF)
