Design of Embedded Speech Recognition System
ZHOU Zhi-qiang & YAO Li-ming

Abstract
This paper describes the process and the basic principles of speech recognition. The algorithm and signal processing technology of speech recognition are studied in depth. At the same time, the MATLAB software is used to simulate the signal processing method, and verify the feasibility of the method. The system uses STM32F103ZE as the main control chip, and has good expansibility. Speech recognition module uses LD3320 chip. The chip can complete the task of speaker-independent speech recognition.
