Limitations
Voice is the most natural communication medium, but the information that can be provided is limited compared to visual media.
For example, most Internet users try a search term, scan results, then adjust the search term to eliminate irrelevant results. They may take two or three quick iterations to get a list that they are confident will contain what they are looking for. The equivalent approach is not practical when results are spoken, as it would take far too long. In this case, a multimodal interaction would be preferable to a voice-only interface.
