Abstract
With the development of smart home, speech recognition technology can provide a more convenient way for human–computer interaction, and meanwhile provides a better user experience. A voice control system for smart home based on single-chip computer module STC89C52 and speech recognition module LD3320 is designed in this paper. The electric equipment such as a fan can be controlled by the recognized voice command. The peripheral equipment equipped with a gas sensor, a smoke sensor, and a temperature and humidity sensor can gather the living environment in the room, and the temperature and humidity can be displayed on the OLED. A MP3 player equipped with a speaker can broadcast the voice once the fire or smoke is detected, then the user can be reminded by an alarm. The experiment results show that the system has high stability and high speech recognition rate, which can improve the level of disaster prevention.
