Popis: Previous studies have revealed that the perception and comprehension of synthetic speech may be attributed to increased processing demands in short-term memory as reflected in serial-order and preload paradigm tasks. Additionally, it has been consistently shown that the perception of synthetic speech improves with moderate amounts of training. The present study was conducted to determine if the increased perceptual effects of training for synthetic speech can be attributed to a reduction of short-term memory load. Two groups of subjects were tested with synthetic speech using the same comprehension and high cognitive processing tasks before and after training. One group was trained with synthetic speech and the other group acted as the control, receiving no training between the pretest and post-test interval. Results reveal similar increases in comprehension based on previous synthetic speech studies for the trained group. Moreover, these results suggest that training on synthetic speech promotes better allocation of attentional resources which result in improved performance on working memory capacity measures.
