Microsoft Cognitive Speaker Recognition API -注册-无效音频400错误

Question

我正在尝试将音频文件从改进上载到扬声器识别，但收到无效音频错误：

请找到下面的代码：

 public void  createEnrollment(String verficationId,String file) throws IOException {

    RequestBody videoBody = RequestBody.create(MediaType.parse("application/octet-stream"), file);
    MultipartBody.Part vFile = MultipartBody.Part.createFormData("audio", file, videoBody);

    ApiInterface service = RetrofitClientInstance.getRetrofitInstance().create(ApiInterface.class);
    Call<List<EnrolmentResult>> call = service.postAudioAndGetResponse(API_KEY,verficationId,vFile);
    call.enqueue(new Callback<List<EnrolmentResult>>() {
        @Override
        public void onResponse(Call<List<EnrolmentResult>> call, Response<List<EnrolmentResult>> response) {
            Log.d("Result", response.body().toString());
        }
        @Override
        public void onFailure(Call<List<EnrolmentResult>> call, Throwable t) {
            //progressDoalog.dismiss();
            Log.d("Error", t.getMessage());
                }
    });

}


 public interface ApiInterface {

@Multipart
@POST("identificationProfiles/{verificationProfileId}/enroll")
Call <List<EnrolmentResult>> postAudioAndGetResponse(@Header("Ocp-Apim-Subscription-Key") String keyValue,
                                                     @Path("verificationProfileId") String id,
                                                     @Part MultipartBody.Part file
                                                     );

 }

音频为.wav格式，并转换为以下格式：

容器WAV编码PCM速率16K采样格式16位通道单声道

当我从邮递员那里发送同样的邮件时，我得到的响应是202成功

您是否尝试过使用application/json作为媒体类型？...看起来所有的调用都希望如此，即使我们发送的是二进制文件
