Abstract:
An apparatus for creating a biased normalizing template suitable for use by a speaker verification system to authenticate a speaker based on a speech pattern, the speech pattern being representative of a first set of speech characteristics, said apparatus comprising:an input for receiving an input signal representative of a speech pattern from a given speaker; a processing unit coupled to said input for receiving said input signal, said processing unit being operative for processing said input signal and a first data element representative of a speaker independent normalizing template representative of a second set of speech characteristics to derive a second data element representative of an altered version of the user independent normalizing template, said second data element forming a biased normalizing template representative of a third set of speech characteristics, where the third set of speech characteristics is a combination of the first set of speech characteristics and the second set of speech characteristics; an output for releasing an output signal conveying the biased normalizing template suitable for use by a speaker verification system.
