16. The system in accordance with claim 15 wherein the processor determines the speaker verification in response to a dual-scoring soft decision margin combination of the UBM-independent speaker-normalized score and the text-dependent speaker verification score.
15. A system for speaker verification comprising: an audio receiving device for receiving an utterance from a speaker and converting the utterance to an utterance signal; and a processor coupled to the audio receiving device for determining speaker verification in response to the utterance signal, wherein the processor determines speaker verification in response to a Universal Background Model (UBM)-independent speaker-normalized score by determining a text-independent speaker verification score in response to the utterance signal, the text-independent speaker verification score determined in response to a speaker-dependent text-independent Gaussian Mixture Model (GMM) of the utterance; determining a text-dependent speaker verification score in response to the utterance signal, the text-dependent speaker verification score determined in response to a continuous density Hidden Markov Model (HMM) of the utterance signal aligned by a Viterbi decoding; and determining the UBM-independent speaker-normalized score in response to a relationship between the text-dependent speaker verification score and the text-independent speaker verification score, the relationship being based on a difference between the text-independent speaker verification score and the text-dependent speaker verification score.
