示例

以下示例显示了 或 SpeechRecognizer 对象的 事件的SpeechRecognitionEngine处理程序SpeechRecognized，以及有关关联的 RecognitionResult的一些信息。

// 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}: {2}",
    e.Result.Grammar.Name, e.Result.Audio.Duration, e.Result.Text);

  // 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);
  }
}

注解

此类派生自 RecognizedPhrase 并提供有关语音识别的详细信息，包括以下内容：

• 属性 Grammar 引用 Grammar 识别器用于标识语音的 。

• 属性 Text 包含短语的规范化文本。 有关文本规范化的详细信息，请参阅 ReplacementText。

• 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 Alternates 包含对象的集合 RecognizedPhrase ，这些对象表示音频输入的其他候选解释。 有关详细信息，请参阅 Alternates。

• 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。 每个都包含 RecognizedWordUnit 相应单词的显示格式、词法格式和发音信息。
