摘 要：Raspberry Pi is a credit card sized Linux computer based on ARM11 architecture.Because of its small size,low power consumption and powerful performance,a robot controller is a suitable role for it to play.As a robot with artificial intelligence,speech recognition for controlling the robot and voice feedback to users is key parts of the entire system.In this essay,a robot called Lisa is assembled,and a speech control and interactive system is implemented based on Google voice API which is a voice recognition engine provided as a cloud service.In order to analysis complex voice commands,a semantic method is developed to catch key words from command sentences.Then try to make a pattern match between key words and instruction set build-in the robot control system.The speech recognition control and interactive system is effective and well behaved after experimental verification.
