Research on the Integration of Sound Control Module in Intelligent Door Control System Based on STM32 Microcontroller
A voice control module of intelligent door control system based on STM32 single chip microcomputer is designed and implemented.The voice control operation of the door control system is realized by preprocessing and feature extraction of the voice signals collected by the microphone array of the high-sensitivity Micro Electro Mechanical System(MEMS),and combining with the deep neural network model for voice recognition.The experimental results show that the module can achieve more than 98%voice wake-up rate and command word recognition rate in quiet environment,and its performance remains high even in noisy environment.
