Model adaptation based on improved variance estimation for robust speech recognition

This paper proposes a model adaptation algorithm based on improved variance estimation for noise robust speech recognition. In this algorithm, the approximate closed-form variance estimation is extended from the feature space to the model space and the dynamic parameters of the hidden Markov model (...
