Research on HMM-Based Speech Retrieval Algorithm

Speech retrieval refers to the data mining technology that delivers results after retrieving in massive speech data according to the query items entered by users. This paper briefly discusses the reasons for the development of voice retrieval and the current development of voice retrieval technology, mainly explains the basic principle of Hidden Markov Model, and analyzes the three basic problems to be solved by its algorithm. On this basis, HMM is adopted for speech recognition, and simulated by MATLAB. Afterwards, the performance of HMM is analyzed in accordance with the simulation results.
