Speaker Recognition with Random Digit Strings Using Uncertainty Normalized HMM-based i-vectors

13 Jul 2019Nooshin MaghsoodiHossein SametiHossein ZeinaliThemos~Stafylakis

In this paper, we combine Hidden Markov Models (HMMs) with i-vector extractors to address the problem of text-dependent speaker recognition with random digit strings. We employ digit-specific HMMs to segment the utterances into digits, to perform frame alignment to HMM states and to extract Baum-Welch statistics... (read more)
