SpeechClient.PollUntilComplete挂起

Question

使用下面的代码，PollUntilComplete（）方法永远不会返回

string uri = $"gs://{bucket}/{selectedFile}";
RecognitionConfig config = new RecognitionConfig()
{
   Encoding = RecognitionConfig.Types.AudioEncoding.Linear16,
   SampleRateHertz = int.Parse(sampleRateComboBox.Text),
   LanguageCode = "en",
   Model = "default"
   };
RecognitionAudio audio = RecognitionAudio.FromStorageUri(uri);
if (audio.Content != null)
{
   var longOperation = speech.LongRunningRecognize(config, audio);
   toolStripStatusLabel1.Text = "Processing: " + selectedFile;
   Console.WriteLine("Transcript: ");
   longOperation = longOperation.PollUntilCompleted(null, null, 
     new Action<LongRunningRecognizeMetadata>((LongRunningRecognizeMetadata obj) =>
     {
        Console.WriteLine($"Last Update Time: {obj.LastUpdateTime.ToDateTime()
           .ToString()}, Percent Complete: {obj.ProgressPercent}");
     }));
   }

如果我使用gcloud CLI启动该过程，它将起作用。所以我知道源文件和帐户凭据是有效的。关于可能出什么问题的任何建议？

请参阅下图，我的回叫花了几秒钟。但是我的音频文件长约20秒。可能是您的文件更长。
