科大讯飞语音评测web api调研
文档地址：https://doc.xfyun.cn/rest_api/%E8%AF%AD%E9%9F%B3%E8%AF%84%E6%B5%8B.html
-
评测需要： 一段语音(不超过3分钟) + 试卷(需要评测文本内容)
-
异常情况
-
VLC播放pcm文件命令
/Applications/VLC.app/Contents/MacOS/VLC --demux=rawaud --rawaud-channels 1 --rawaud-samplerate 16000 /Users/xmly/Desktop/testAudioPCM.raw -
java demo 调用语音评测，测试内容为7个单词长度的句子
This is an example of sentence test.
所用时长：
47s左右
后续发现，在官方提供的HttpUtil中
while ((line = in.readLine()) != null){
result += line;
}
此部分耗时44s
调整代码后证明，调用科大讯飞web api平均耗时在3-4s；
