In this paper, a hybrid MMI-connectionist / hidden Markov model (HMM) speech recognition system for the Wall Street Journal (WSJ) database is presented. The HMM part of this system uses discrete probability density functions (pdf). The neural network (NN) is used to replace a classical vector quantizer (VQ) like a k-means or LBG algorithm, which are typically used in discrete HMM systems. The N...
