Learning outcomes
After completing this course, the student will understand the basic techniques used in speech recognition. He or she will be able to implement the front-end used for extracting relevant information from the speech signal. The student will have a detailed understanding of the mathematical principles of hidden Markov models (HMMs) that are used to model the data provided courtesy of the front-end. The student will be able to calculate quantities that are requred to train HMMs and use them for pattern classification. The student will be able to implement a simple HMM-based speech recognition system.
