With the development of Internet technology and automation, smart home technology has become the one of the most popular directions of the internet of things. The intelligent trash based on nonspecific speech recognition chip LD3320 made by ICRoute with nonspecific speech recognition algorithm to finish the intelligent voice recognition and voice control and achieve the function of omnidirectional movement, noncontact intelligent opening and closing, measurement. In the simulative environment of the working, the experiment tests the rate of correct recognition. In the normal working environment, the correct recognition rate reaches 88.4%, proving the design can finish the functions and actions within 2 meters.
