如题使用centos 系统可以吗？
系统使用win，虚机中安装的centos 可以吗？

recorder默认的是32bit 44100的码率导致播放语速过快，修改为16bit 48000的码率后，voiceoutput可以正常语速播放，然而audioplayer无法播放歌曲，而play status 显示的是正在播放
---以下内容2018-3-19更新
我在dcs_client.js中，将 原本的“用RecorderWrapper包一下，是因为怕播放指令执行的时候，管道已经输出了一点东西了，复用一下RecorderWrapper的缓存功能”重新改为了之前版本没有用recordwrapper的代码，这个时候audioplayer开始工作了，可以正常的输出音频声音，但是voiceoutput停止了输出，类似于 “小度小度，今天的天气”等的回答全都没了声音。

请问申请 access_token 用到的REDIRECT_URI 是什么？

在播放过程中会被自己的声音打断，然后进入“你好...抱歉我不太确定你说了什么...你好...” 的无限循环中~

在树莓派上，获取oauth之后，运行. dcs_test.sh可以听到“抱歉，我不太确定你说了什么”，但运行node index.js会迅速退出，可能是什么原因？

以下是log：

How to customize awakening words?
I found that the action is to wake up through NEW_WAKE this procedure to resolve, and did not see the loading of a custom wake-up word.
