<p><P>PROBLEM TO BE SOLVED: To provide a speaker matching device improved in the ratio (matching ratio) capable of determining whether a speaker is identical person or pretender. <P>SOLUTION: A matching pattern generation part 1 generates a matching pattern of continuous numbers by discarding and replacing a number with which it is difficult to decide whether the person himself or herself is a pretender with a new number on the basis of an evaluation result obtained by a number unit score evaluation part 10, and the presents the matching pattern to a user. A pattern dependency precision prediction/threshold setting part 9 predicts precision and sets a threshold based upon the numbers constituting the matching pattern. The number unit score evaluation part 10 evaluates similarities, found by the numbers between a speech that the user speaks and a previously registered speech, by precision evaluating functions by the numbers. A speaker decision part 8 decides a similarity to the matching pattern by using the threshold set by the pattern dependency precision prediction/threshold setting part 9. Replacement in number chain units is possible. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
