示例

以下示例演示 、 SpeechRecognizer.SpeechRecognized或 Grammar.SpeechRecognized 事件的处理程序SpeechRecognitionEngine.SpeechRecognized以及与 对象关联的RecognitionResult某些信息。 RecognitionResult 类是从 RecognizedPhrase 类派生的。

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("Recognition result summary:");
  Console.WriteLine(
    "  Recognized phrase: {0}\n" +
    "  Confidence score {1}\n" +
    "  Grammar used: {2}\n",
    e.Result.Text, e.Result.Confidence, e.Result.Grammar.Name);

  // Display the semantic values in the recognition result.
  Console.WriteLine("  Semantic results:");
  foreach (KeyValuePair<String, SemanticValue> child in e.Result.Semantics)
  {
    Console.WriteLine("    The {0} city is {1}",
      child.Key, child.Value.Value ?? "null");
  }
  Console.WriteLine();

  // Display information about the words in the recognition result.
  Console.WriteLine("  Word summary: ");
  foreach (RecognizedWordUnit word in e.Result.Words)
  {
    Console.WriteLine(
      "    Lexical form ({1})" +
      " Pronunciation ({0})" +
      " Display form ({2})",
      word.Pronunciation, word.LexicalForm, word.DisplayAttributes);
  }

  // Display information about the audio in the recognition result.
  Console.WriteLine("  Input audio summary:\n" +
    "    Candidate Phrase at:       {0} mSec\n" +
    "    Phrase Length:             {1} mSec\n" +
    "    Input State Time:          {2}\n" +
    "    Input Format:              {3}\n",
    e.Result.Audio.AudioPosition,
    e.Result.Audio.Duration,
    e.Result.Audio.StartTime,
    e.Result.Audio.Format.EncodingFormat);

  // Display information about the alternate recognitions in the recognition result.
  Console.WriteLine("  Alternate phrase collection:");
  foreach (RecognizedPhrase phrase in e.Result.Alternates)
  {
    Console.WriteLine("    Phrase: " + phrase.Text);
    Console.WriteLine("    Confidence score: " + phrase.Confidence);
  }
}

注解

此类包含有关在语音识别操作期间处理的字词和短语的详细信息，包括以下内容：

• 属性 Grammar 引用 Grammar 识别器用于标识输入的 。

• 属性 Text 包含短语的规范化文本。

• 属性 Semantics 引用结果中包含的语义信息。 语义信息是键名称和关联的语义数据的字典。

• 属性 Words 包含对象的有序集合 RecognizedWordUnit ，这些对象表示输入中每个识别的单词。 每个单词单元都包含相应单词的显示格式、词法格式和发音信息。

• 属性 ReplacementWordUnits 包含有关专用词替换的信息。

• Homophones和 HomophoneGroupId 属性包含有关具有相同或类似发音的识别替代项的信息。

• 属性的值 Confidence 指示由语音识别器分配的确定性程度，即识别的短语与输入匹配。

语音识别器返回继承自 RecognizedPhrase的 RecognitionResult 对象的识别结果。 识别结果 Alternates 属性包含一个有序的对象 RecognizedPhrase 集合，其中每个对象都是识别器输入的可能匹配项。
