摘要
智能音响控制系统选取STM32和LD3320作为系统控制核心芯片和语音控制模块,由LD3320将声音信号识别,并将识别到的结果通过SPI串口发送给STM32,若结果识别成功,STM32将执行指令通过蓝牙模块传输到MP3模块或者使继电器驱动喇叭工作。智能音响控制系统通过语音控制有效实现歌曲的播放、暂停播放等功能,并且可以通过继电器对家用电器进行简单控制。
STM32 and ld3320 are selected as the core chips and voice control modules in the intelligent audio control system.Ld3320 recognizes the sound signal and sends the recognized result to STM32 through SPI serial port.If the result is recognized successfully,STM32 will transmit the executive instruction to MP3 module through Bluetooth module or make the relay drive the horn to work.The intelligent audio control system can effectively realize the functions of song playing,pause playing and so on through voice control,and can simply control the household appliances through the relay.
