Question

我正在尝试根据https://westus.dev.cognitive.microsoft.com/docs/services/563309b6778daf02acc0a508/operations/5645c3271984551c84ec6797使用MS Azure扬声器识别API（java）。我能够获得一个identificationProfileId。尝试注册时出现错误。这是我的报名方式 -获取注册音频的WAV文件 -转换为base64（通过在线服务） -将base64作为内容与IdentificationProfileId一起作为注册请求的内容。我对b64部分感到怀疑

我收到“无效的音频格式：不是WAVE文件-没有RIFF标头”

我知道该服务需要根据文档以PCM编码的音频。

有人可以让我知道如何将wav音频转换为可以传递到注册REST端点的所需格式。

Answer 1

如果我像下面的代码片段一样传递文件，则可以正常工作！

 File file = new File("/Users/jdoe/Desktop/vp/v5.wav");
 request.setEntity( new FileEntity(file, ContentType.APPLICATION_OCTET_STREAM) );

Answer 2

不要使用base 64，只能使用原始字节数组数据。
