Abstract
This study compares the effects of shadowing and those of repeating during six repetition trials in terms of two aspects: reproduction rate and type of reproduced words. 48 university students performed both shadowing and repeating six times each, and their recorded voices were analyzed to see if there were any differences between the two kinds of training methods in terms of the reproduction rate and the number of function and content words reproduced correctly on each repetition trial. The results indicated that four or five repetition trials were enough to improve the rate of reproduction to a level near the ceiling point. It was also found that the participants could reproduce more content words with shadowing than with repeating, whereas some reduced function words were reproduced from the first trail of repeating, all of which may reflect differences in the language processing between shadowing and repeating performances.
