Design of Speech Recognition System
Abstract: This design introduces the principles of speech recognition system, function and recognition algorithm, etc. And the steps of the recognition are phonetic acquisition, preprocessing, feature extraction and pattern matching parameters. By comparing the different characteristics of various algorithms, this design adopts the DTW algorithm in pattern matching, and the algorithm can effectively extract the high frequency of isolated word speech. On the platform of MATLAB by means of GUI interaction, simulation implements the speech recognition from 0 to 9 isolated words, which can be repeatedly used and easy to operate with a high recognition rate.
Key Words: Speech recognition system; Recognition algorithms; MATLAB
