Question

我正在使用Google Speech API for C＃，并使用LongRunningRecognize来检索结果，如下所示：

var speech = SpeechClient.Create();
var longOperation = speech.LongRunningRecognize(new RecognitionConfig()
{
    Encoding = GlobalVariables.Encoding,
    SampleRateHertz = GlobalVariables.SampleRateHz,
    LanguageCode = GlobalVariables.Language,
}, RecognitionAudio.FromStorageUri("gs://bucketname/" + TargetFileName));
longOperation = longOperation.PollUntilCompleted();
var response = longOperation.Result;

StringBuilder tw = new StringBuilder();

foreach (var result in response.Results)
{
    foreach (var alternative in result.Alternatives)
    {
        Console.WriteLine($"Transcript: { alternative.Transcript}");
        tw.AppendLine(alternative.Transcript);
    }
}

TranslatedText = tw.ToString();

那很好，我得到了结果-但是：我正在使用很大的文件（大约20-30分钟的音频文件），并且我希望看到中间结果。所以我发现我可以像这样以某种方式使用异步方法：

Task analyze = Task.Run(async () =>
{
    var speech = SpeechClient.Create();
    Task<Operation<LongRunningRecognizeResponse, LongRunningRecognizeMetadata>> longOperation = speech.LongRunningRecognizeAsync(new RecognitionConfig()
    {
        Encoding = GlobalVariables.Encoding,
        SampleRateHertz = GlobalVariables.SampleRateHz,
        LanguageCode = GlobalVariables.Language,
    }, RecognitionAudio.FromStorageUri("gs://bucketname/" + TargetFileName));

    while (!longOperation.IsCompleted)
    {
        if(longOperation.Result != null && longOperation.Result.Metadata != null)
        {
            LongRunningRecognizeMetadata meta = longOperation.Result.Metadata;
            ProgressValue = meta.ProgressPercent;

            //Add results to variable "TranslatedText" here -how?
        }
    }
});

await analyze;

虽然我无法使它正常工作，并且在这种情况下对语音API的记录也不够好，至少我还没有发现任何可以解决这种情况的东西。

有人可以帮我吗？

谢谢！
