This research aims to assist users to seek information efficiently while interacting with speech-based information, particularly in multimedia delivery, and reports on an experiment that tested two speech-based designs for communicating multiple speech-based information streams efficiently. In this experiment, a high-rate playback design and a concurrent playback design are investigated. In the high-rate playback design, two speech-based information streams were communicated by doubling the normal playback-rate, and in the concurrent playback design, two speech-based information streams were played concurrently. Comprehension of content in both the designs was also compared with the benchmark set from regular baseline condition. The results showed that the users’ comprehension regarding the main information dropped significantly in the high-rate playback and the concurrent playback designs compared to the baseline condition. However, in answering the questions set from the detailed information, the comprehension was not significantly different in all three designs. It is expected that such equeryfficient communication methods may increase productivity by providing information efficiently while interacting with an interactive multimedia system.
