RecognizedAudio.StartTime 屬性

定義

命名空間:

System.Speech.Recognition

組件:

System.Speech.dll

套件:

System.Speech v9.0.0-preview.6.24327.7

來源:

RecognizedAudio.cs

取得辨識作業開始時的系統時間。

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

public DateTime StartTime { get; }

member this.StartTime : DateTime

Public ReadOnly Property StartTime As DateTime

屬性值

DateTime

辨識作業開始時的系統時間。

範例

下列範例會 SpeechRecognitionEngine.SpeechRecognized 處理 或 SpeechRecognizer.SpeechRecognized 事件，並將輸出處理到與辨識結果相關聯之已辨識音訊的主控台資訊。

// 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.  
}  

備註

屬性 StartTime 會在辨識作業開始時取得系統時間，這對於延遲和效能計算很有用。

屬性 AudioPosition 會取得輸入裝置所產生音訊資料流程中的位置。
