CS 753: Automatic Speech Recognintion

Introduction to the statistical approach for automatic speech recognition (ASR)

• Weighted Finite State Transducers and their Application to ASR

• Acoustic Signal Processing for ASR

• Acoustic models: Hidden Markov Models, Gaussian Mixture Models, Baum-Welch Maximum Likelihood


• Discriminative Training of Acoustic Models: Maximum Mutual Information, Minimum Word/Phone Error Criteria

• Acoustic models continued: Neural network models (Deep feed-forward neural networks, convolutional neural

networks and recurrent neural networks)

• Pronunciation models: Pronunciation dictionaries, grapheme-to-phoneme models, feature-based models

• N-gram language models: estimation, smoothing

• ASR decoding problem: search algorithms, Viterbi estimation, finite-state transducer optimizations

Programming assignments for a few of the above listed topics, along with a final research project, will be part of the
