基于4麦克风阵列（ReSpeaker 4-Mic Array）的娱乐功能包括点歌，讲故事，相声，评书，天气预报和股市行情等是淘宝上买的套件，人家已经完全布好并给了镜像文件，直接烧录到SD卡即可树莓派3B+上使用。上面附有说明书，运行程序前需要先进入虚拟环境，否则无法正常运行。使用前，先授权，有效期只有一个月，运行 dueros-auth 获取百度的授权。授权的文件保存在/home/pi/.avs.json。但是麦克风阵列（ReSpeaker 4-Mic Array）影响我使用树莓派的其它引脚，所以打算改成基于USB麦克风的，亚马逊官网查了一下，人家本来就是针对USB麦克风的，我这行为类似于历史倒退，但适合我的需求，我喜欢，那就折腾吧！首先，汉语搜不到任何资料，自己将文件夹内的.py文件翻了个遍，也没有改成，老是提示 arecord录音错误，找不到录音设备（虽然安了pyaudio，看来没有使用，倍感清醒），感觉不是我理解的问题，应该解决硬件问题，单句执行 arecord -d 3 -c 2 -r 44100 -f S16_LE xiaoben.wmv 发现果真不能用（见我的“树莓派（USB麦克风和麦克风阵列）录音和播放”https://blog.csdn.net/weixin_44345862/article/details/101355529）
