Building context-dependent DNN acoustic models using Kullback-Leibler divergence-based state tying
ICASSP 2015accepted
Deep neural network (DNN) based speech recognizers have recently replaced Gaussian mixture (GMM) based systems as the state-of-the-art. HMM/DNN systems have kept many refinements of the HMM/GMM framework, even though some of these may be suboptimal for them. One such example is the creation of conte…
