<p><P>PROBLEM TO BE SOLVED: To solve a problem that a conventional device which reduce confirming operation etc., by detecting an extraction error from extracted information reliability of an input speech cannot specify an error of proper reliability calculation under conditions which are different from those, at the system designing, since the device finds the reliability from only speech recognition likelihood. <P>SOLUTION: A speech interactive processing device is equipped with a speech understanding section which outputs a meaning item candidate and its likelihood, by performing speech recognizing processing and meaning analytic processing for an input speech; a reliability calculating section which calculates the likelihood of a meaning item, a correction parameter for measuring item reliability correction; a reliability correcting section which calculates the correction reliability of the meaning item from the reliability; an interactive management section which determines, by using the correction reliability whether a user is made to confirm whether the meaning item is correct or incorrect, to output an answer sentence to the user, and further writes interaction with the user as interaction history data in an interaction history storage part; and a correction parameter adjustment section which updates the correction parameter, by using the interaction history data. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
