備註

限制式或文法定義可與語音辨識器相符的口說字詞和片語。

您可以指定其中一個預先定義的 Web 服務文法，也可以建立自己的自訂文法 (請參閱SpeechRecognitionGrammarFileConstraint、SpeechRecognitionListConstraint和SpeechRecognitionVoiceCommandDefinitionConstraint) 隨您的應用程式一起安裝。

即使Constraints屬性中未指定任何條件約束，CompileConstraintsAsync也必須在RecognizeAsync或RecognizeWithUIAsync之前呼叫。

若要使用 Web 服務條件約束，必須在 [ 設定 ] 中啟用語音輸入和聽寫支援，方法是在 [設定 - > 隱私權 - > 語音]、筆跡和輸入中開啟 [瞭解我] 選項。 For more detail on recognition constraints, see "Recognize speech input" in Speech recognition.

注意

使用 SpeechRecognitionListConstraint 搭配 SpeechRecognitionTopicConstraint ，在冗長的聽寫會話期間提高辨識精確度。 這可讓您提供一組您認為在聽寫期間可能會使用的網域特定關鍵字。
