Study on Speech Recognition Control Strategy Based on Regular Expression

Abstract

A new control strategy combined regular expression and speech control system of service robot was proposed in the paper.The former implements pattern detection for the contents of speech recognition,and the later implements control strategies for the service robot based on the pattern detected.The regular expressions used to detect pattern was built through analyzing the source texts, the client voice engine used for speech recognition was built with Microsoft SAPI,the control strategies was examined on service robot platform and proved to be effective,practical and fast.The method proposed in this paper enables the robot to understand multiple expressions way for the same meaning,which makes the human-robot voice interactive more flexible and natural.
