.NET Framework
スピーチを認識するSpeechRecognitionEngineクラス

構文

• SpeechRecognitionEngine（）
• SpeechRecognitionEngine.LoadGrammar（文法文法）
• SpeechRecognitionEngine.SetInputToDefaultAudioDevice（）
• SpeechRecognitionEngine.RecognizeAsync（RecognizeModeモード）
• GrammarBuilder（）
• GrammarBuilder.Append（選択肢の選択肢）
• 選択肢（params文字列[]の選択肢）
• 文法（GrammarBuilder Builder）

パラメーター

備考

フリーテキストの口述を非同期的に認識

using System.Speech.Recognition;

// ...

SpeechRecognitionEngine recognitionEngine = new SpeechRecognitionEngine();
recognitionEngine.LoadGrammar(new DictationGrammar());
recognitionEngine.SpeechRecognized += delegate(object sender, SpeechRecognizedEventArgs e)
{
    Console.WriteLine("You said: {0}", e.Result.Text);
};
recognitionEngine.SetInputToDefaultAudioDevice();
recognitionEngine.RecognizeAsync(RecognizeMode.Multiple);

制限されたフレーズセットに基づいて音声を非同期的に認識する

SpeechRecognitionEngine recognitionEngine = new SpeechRecognitionEngine();
GrammarBuilder builder = new GrammarBuilder();
builder.Append(new Choices("I am", "You are", "He is", "She is", "We are", "They are"));
builder.Append(new Choices("friendly", "unfriendly"));
recognitionEngine.LoadGrammar(new Grammar(builder));
recognitionEngine.SpeechRecognized += delegate(object sender, SpeechRecognizedEventArgs e)
{
    Console.WriteLine("You said: {0}", e.Result.Text);
};
recognitionEngine.SetInputToDefaultAudioDevice();
recognitionEngine.RecognizeAsync(RecognizeMode.Multiple);
