We report on a study exploring the use of voice commands by older adults browsing the Web. We sought to develop an understanding of how such commands might make Web navigation and access to Web accessibility transformations easier. The results suggested a number of surprising difficulties in using spoken commands. Some were due to general confusions about how to use the browser. Some were due to mismatches between what was natural to say versus what was natural to do with a mouse. We review some of these difficulties and discuss possible underlying reasons. Finally, we suggest interface changes that would make an otherwise well-engineered user interface better suited for voice commands.
