✦ Synopsis
The objective of this study was to compare empirically the ef fect on performance and satisfaction of a menu and a front-end voice interface to a commonly used spreadsheet software package . In this study , the type of human -computer interface used (standard keyboard / mouse use of menus or keyboard / mouse with a voice front-end) is expected to influence user performance (task completion time and error rates) and satisfaction . The user's novice / expert classification is expected to interact with these two types of interfaces to influence the ef ficiency of the user's performance . The results suggest that there are significant relationships between task performance and level of expertise / type of interface and between user attitudes and type of interface . In general , the front-end voice interface users performed worse and had less favorable attitudes towards the software tool than the menu interface users .
