Abstract: Speech recognition technology is widely applied in the field of intelligent robot control. In order to improve the human-machine interaction level of humanoid robots, a human-machine interaction intelligent control system is designed in this paper, which uses a bipedal walking robot mobile platform as the carrier, a speech recognition module as the medium, and a speaker module as the response. Firstly, a reasonable hardware system was built to ensure smooth communication between modules; then, the control system was tested in quiet, noisy, enclosed, and open environments respectively, and the expected results were achieved. This article studies and practices the application of speech recognition technology in the design of control systems for bipedal walking robots. The design analysis and verification results provide reference for improving the intelligent design research of bipedal walking robots.
