用我的试一试, 一楼有:

按照你提供的这两个 key ，确实可以。

make flash  固件烧录成功之后， 重启ESP32， 播放声音 下面定义的声音；

#define TTS_TEXT "欢迎使用乐鑫音频平台，想了解更多方案信息请联系我们"

大概的流程应该是， WIFI 连接成功====》通过 http 方式  使用上面两个key  将TXT 发给百度=====》 百度译解出语音文件 MP3=====》 发给ESP32=====》 ESP32 接收到MP3之后 通过 语音解码ic 播放出来 

这个过程中有2个部分比较模糊

1.  代码上看起来很模糊，封装得太密了，目前只是大概的看出 一条 管道  WIFI-->http_stream-->mp3_decoder-->i2s_stream-->[codec_chip]

2.  我在百度上 同样创建了应用，使用应用的key 但是 就是不成功~~~~ 晕哥 是不是还有其他要注意的地方 我遗漏了呢？ 这方面能给个大概的介绍吗？

我的上电没有提示音，难受中，也没有显示token错误之类的

最近编辑记录 wenkumk (2018-07-10 14:29:27)

有的，只是我后面编辑删了

是的呢

录音是别的例程，具体怎么使用忘记了.

测试这个本地音乐播放，判断声卡和功放是否正常。

那看不出来问题.

还有这种操作？ ............
