Abstract
In our paper, we present evaluation results for VoiceBrowse, an interactive system allowing users to access content and services from the Internet via voice control. We compare two user groups, inexperienced and experienced computer users, regarding their performance and judgment of two versions of the system differing in the dialog initiative. Furthermore we investigate the usability of the systems after long-term usage (simulated by fifteen minutes practise). We find that even inexperienced computer users know from the beginning how to speak to the system, which contrasts assumptions in the related literature. Inexperienced uses perform as good as experienced users with both systems before and after the training. We also compare judgments of the systems before and after the training.
