Developers of visual Interface Design Environments (IDEs), like Microsoft Visual Studio and Java
NetBeans, are competing in producing pretty crowded graphical interfaces in order to facilitate
completion of interface-design tasks. Previous studies have shown that such interfaces cause the
user to experience information overload as well as they create a fertile environment for usability
problems. In this paper, we empirically investigate speech as an input and output means for solving
usability problems with GUI interaction metaphors and enhancing usability of visual IDEs. The
empirical investigation aimed at measuring usability of two experimental ID toolkits: typical
visual-only (TVOID) and multimodal (MMID) in terms of efficiency, effectiveness and satisfaction.
Usability of these two environments was tested twice, over two experimental phases, by four
independent groups of users. The first experimental phase was for measuring usability by novel
users in order to explore how learnable each of the two experimental toolkits would be. The second
phase aimed at measuring usability by well-trained users to study experienced user performance
when using a speech recognition ID.
