Design of Speech Recognition Robot Based on MCU

Abstract

Speech control technology is one of the important technologies at present, that is broadly researched and applied and is valuable for human-machine interactive intelligent control system. The design used Sunplus SPCE061A as voice recognition to collect, analysis, identify and implement correspondent judgment to the voice. As the core processor of the robot, AT89S52 collect, analysis and process various signals. AT89C2051 is used to be the robot arm servo motor drive chip. Throughout the robot system, the core chip uses parallel port and serial port to realize communication and set the control of authority. The system has been tested and the result shows its high accuracy of speech recognition and powerful control ability.
