Abstract: In order to improve people's quality of life and solve the problem that the traditional range hood needs to be manually set during use, an intelligent range hood control system with diverse functions will be designed to use voice commands to select the working state of the range hood. It has the functions of selecting the wind force, lighting switches and natural gas leakage detection through voice control. The basic requirements of modern range hood are analyzed, and the hardware design scheme of intelligent range hood based on voice control is proposed; The details of each hardware module of the intelligent range hood are constructed; Finally, the corresponding voice commands are used to test the wind control, lighting switch and alarm functions of the designed intelligent range hood system, which proves the accuracy and practicality of the design.

Key words: Intelligent range hood, Single chip, Speech recognition, Hardware design
