Design of Voice Control Lighting System Based on LD3320

With the rapid development of electronic technology, as well as the improvement of living standards, the concept of smart home system began to move to the public. In the light of people's demand, a kind of voice control home lighting system is designed. The system uses STC11L08 XE microcontroller, combined with high performance speech recognition chip LD3320 as the main control module, using single-chip microcomputer and relay as the lighting system LED lamp control node. The main control module and the control node are connected through the n RF24L01 wireless transceiver chip. The experimental results show that the recognition rate of the system is high, and the LED lamp can be accurately controlled.
