Python2.7对接科大讯飞的语音合成和语音识别接口

小Z正在尝试科大讯飞的语音合成和语音识别的接口调用。

须要注意的是：

1.白名单要在个人应用中配置，生效有5到10分钟的延迟，配置不正确会报错：

 {"code":"10105","data":"","desc":"illegal access|illegal client_ip: XXXXXX","sid":"XXXX"}

2.语音识别和语音合成使用不一样的APPKEY，配置的时候要检查清楚，不然会报错：

 {"code":"10105","data":"","desc":"illegal access|no appid info","sid":"XXXX"}
