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.

Famous quotes containing the word limitations:
“Growing up means letting go of the dearest megalomaniacal dreams of our childhood. Growing up means knowing they can’t be fulfilled. Growing up means gaining the wisdom and skills to get what we want within the limitations imposed by reality—a reality which consists of diminished powers, restricted freedoms and, with the people we love, imperfect connections.”
—Judith Viorst (20th century)
“The only rules comedy can tolerate are those of taste, and the only limitations those of libel.”
—James Thurber (1894–1961)
“The limitations of pleasure cannot be overcome by more pleasure.”
—Mason Cooley (b. 1927)
