例

次の例では、"ジャズ カテゴリのアーティストリストを表示する" や "アルバムの福音を表示する" などの語句を認識します。 この例では、 イベントのハンドラーを SpeechRecognitionRejected 使用して、音声入力を文章校正の内容と十分な自信を持って照合できない場合に、コンソールに通知を表示し、認識を成功させます。

注釈

イベントはSpeechRecognitionRejected、 クラスと SpeechRecognitionEngine クラスによってSpeechRecognizer発生します。

SpeechRecognitionRejected イベントは、認識操作からの代替候補が受け入れられるほど高い信頼度スコアを持っていない場合に、音声認識エンジンによって生成されます。 拒否されたフレーズに関する詳細情報は、 プロパティを Result 使用して入手できます。

SpeechRecognitionRejectedEventArgs は から RecognitionEventArgs派生します。
