RecognizedAudio.StartTime 属性

public:
 property DateTime StartTime { DateTime get(); };

public DateTime StartTime { get; }

member this.StartTime : DateTime

Public ReadOnly Property StartTime As DateTime

属性值

在识别操作开始时的系统时间。

示例

以下示例处理 SpeechRecognitionEngine.SpeechRecognized 或 SpeechRecognizer.SpeechRecognized 事件，并将有关与识别结果关联的已识别音频的信息输出到控制台。

// Handle the SpeechRecognized event.
void SpeechRecognizedHandler(object sender, SpeechRecognizedEventArgs e)
{
  if (e.Result == null) return;

  RecognitionResult result = e.Result;

  Console.WriteLine("Grammar({0}): {1}",
    result.Grammar.Name, result.Text);

  if (e.Result.Audio != null)
  {
    RecognizedAudio audio = e.Result.Audio;

    Console.WriteLine("   start time: {0}", audio.StartTime);
    Console.WriteLine("   encoding format: {0}", audio.Format.EncodingFormat);
    Console.WriteLine("   position: {0}, duration: {1}",
      audio.AudioPosition, audio.Duration);
  }

  // Add event handler code here.
}

注解

属性 StartTime 获取识别操作开始时的系统时间，这可用于延迟和性能计算。

属性 AudioPosition 获取输入设备生成的音频流中的位置。
