如何通过Java开发实现物联网硬件的声音识别功能

import com.pi4j.io.gpio.*;
import com.pi4j.util.Console;

public class SoundRecognition {
    public static void main(String[] args) throws InterruptedException {
        final Console console = new Console();
        final GpioController gpio = GpioFactory.getInstance();

        // 设置声音传感器引脚
        final GpioPinDigitalInput soundSensor = gpio.provisionDigitalInputPin(RaspiPin.GPIO_04, "SoundSensor");

        console.title("<-- Sound Recognition -->");

        // 等待声音传感器准备就绪
        Thread.sleep(1000);

        // 在声音传感器上添加事件监听器
        soundSensor.addListener((GpioPinListenerDigital) event -> {
            if(event.getState().isHigh()) {
                System.out.println("检测到声音信号");
                // 在这里添加相应的声音识别逻辑
            }
        });

        // 等待退出信号
        console.waitForExit();
        gpio.shutdown();
    }
}
