Abstract : This paper presents the results of five experiments examining the effect of voice generation and recognition systems on dual-task performance. The extent to which asymmetric transfer biased the data in three of these experiments is determined by using statistical techniques and by comparing the data to the results of between-subjects experiments. Generally, subjects performed task combinations better when stimuli for one of the tasks was presented auditorily using a voice generation system rather than visually on a display screen. In contrast, the use of a voice recognition system did not result in better dual-task performance than the use of more conventional input devices. (Author)
