Speech Control System for Robot Based on Raspberry Pi

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.
