28. An apparatus for managing a dialog turn between a user and a spoken dialog system including a computer having computing device-executable instructions, the apparatus comprising: a weight database, controlled by the computer, that stores weights assigned to varying dialog turn information based on statistical information; a dialog analyzer, controlled by the computer, that generates first dialog turn information using dialog information analyzed from a speech uttered by the user; a body expression, controlled by the computer, analyzer that generates second dialog turn information using body expression information analyzed from the user; a synthesizer, controlled by the computer, that synthesizes the first dialog turn information and the second dialog turn information, the synthesizer outputting the synthesized dialog turn information to a weight searcher when the first dialog turn information is different than the second dialog turn information and outputting one selected from the first dialog turn information and the second dialog turn information to a dialog controller when the first dialog turn information is identical to the second dialog turn information; the weight searcher searching the weight database for weights corresponding to the synthesized dialog turn information output from the synthesizer, assigning a positive weight to each of the first and second dialog turn information based on the synthesized dialog turn information and selecting whichever one of the first and second dialog turn information has a greater positive weight; and the dialog controller determining a final dialog turn using the selected one dialog turn information for controlling a dialog between the user and the spoken dialog system.
36. A robot using the apparatus of claim 28 .
