Discriminative MLPs in HMM-based recognition of speech in cellular telephony

Sunil Sivadas, Pratibha Jain, Hynek Hermansky

Deviating from the conventional Hidden Markov Model-Multi-Layer Perceptron (HMM-MLP) hybrid paradigm of using MLP for classification, the proposed discriminative MLP technique uses MLP as a mapping module for feature extraction for conventional HMM-based systems. The MLP is discriminatively trained on the phonetically labeled training data to generate the phoneme posterior probabilities. We achieved a relative word error rate reduction of 15-35% on AURORA Phase 2 continuous digit recognition task defined by ETSI.
