Abstract
A speaker recognition device acquires a registered voice, converts the acquired registered voice to a plurality of property converted voices having respective acoustic properties different from each other, extracts a speaker feature indicative of a characteristic of a speaker from the registered voice, extracts a speaker feature from each of the property converted voices, compares all pairs of speaker features of a part or all of the speaker feature extracted from the registered voice and the speaker features extracted from the property converted voices, and calculates a threshold used for recognition of a speaker of an input voice on the basis of a result of the comparison.
