取得與便是結果相關聯的音訊。
public:
property System::Speech::Recognition::RecognizedAudio ^ Audio { System::Speech::Recognition::RecognizedAudio ^ get(); };public System.Speech.Recognition.RecognizedAudio Audio { get; }member this.Audio : System.Speech.Recognition.RecognizedAudioPublic ReadOnly Property Audio As RecognizedAudio屬性值
與辨識結果相關聯的音訊，如果辨識器是透過呼叫 SpeechRecognitionEngine 或 SpeechRecognizer 執行個體的 null 或 EmulateRecognize 方法來產生結果則為 EmulateRecognizeAsync。
範例
下列範例顯示 SpeechRecognized 事件的處理常式，以及相關聯的部分資訊 RecognitionResult 。
// Handle the SpeechRecognized event.
void SpeechRecognizedHandler(object sender, SpeechRecognizedEventArgs e)
{
if (e.Result == null) return;
// Add event handler code here.
// The following code illustrates some of the information available
// in the recognition result.
Console.WriteLine("Grammar({0}): {1}", e.Result.Grammar.Name, e.Result.Text);
Console.WriteLine("Audio for result:");
Console.WriteLine(" Start time: "+ e.Result.Audio.StartTime);
Console.WriteLine(" Duration: " + e.Result.Audio.Duration);
Console.WriteLine(" Format: " + e.Result.Audio.Format.EncodingFormat);
// Display the semantic values in the recognition result.
foreach (KeyValuePair<String, SemanticValue> child in e.Result.Semantics)
{
Console.WriteLine(" {0} key: {1}",
child.Key, child.Value.Value ?? "null");
}
Console.WriteLine();
// Display information about the words in the recognition result.
foreach (RecognizedWordUnit word in e.Result.Words)
{
RecognizedAudio audio = e.Result.GetAudioForWordRange(word, word);
Console.WriteLine(" {0,-10} {1,-10} {2,-10} {3} ({4})",
word.Text, word.LexicalForm, word.Pronunciation,
audio.Duration, word.DisplayAttributes);
}
// Display the recognition alternates for the result.
foreach (RecognizedPhrase phrase in e.Result.Alternates)
{
Console.WriteLine(" alt({0}) {1}", phrase.Confidence, phrase.Text);
}
}
備註
若要取得與辨識結果中特定文字範圍相關聯的音訊區段，請使用 GetAudioForWordRange 方法。
