a set of classes for identifying a speaker of uttered speech is to be an attribute,
the attribute identification method comprises:
calculating, from input speech, a posteriori probability sequence which is a sequence of posteriori probabilities that each frame of the input speech is a class c,
calculating, from the posteriori probability sequence, a value r(c) of the class c, the value r(c) indicating an extent to which the class c is a correct attribute identification result,
obtaining, from the value r(c), a most probable estimated class c which is a class that is estimated to be a most probable attribute, and
deciding, based on the value r(c ) of the most probable estimated class c , whether the most probable estimated class c is an attribute identification result or the most probable estimated class c is to be rejected.
