整体流程

  1. 脚本监听按钮点击
  2. 调用一言api
  3. 将一言api转为wav文件
  4. 播放wav文件

##前期准备

  1. 音响3.5口 或者蓝牙音响都好

  2. 触发按钮

开始

安装mplay

mplay用于播放媒体文件

sudo apt-get install mplayer

树莓派插入音响，注意从 sudo raspi-config中配置一下音响，有线方式还是蓝牙方式，若是蓝牙方式，则先和牙音响匹配，在把输出端设置为蓝牙

mplayer test.mp3 随便找个文件测试，是否安装成功

腾讯云tts

腾讯云-语音合成

python_SDK根据文档下载例子,配置AppID、SecretId 与 SecretKey

编写下载好的.py文件

vi tcloud_tts.py

修改成这样
