例外狀況

範例

下列範例中的文法包含語言字組，也有不常見的字組：「whatchamacallit」。 使用 Pronunciation 類別的 SrgsToken 屬性新增自訂的內嵌發音，可以改善 「whatchamacallit」 字組的辨識精確度，以及包含該字的整個片語。 此範例會使用來自 Microsoft 通用電話組的手機 (UPS) 來定義自訂發音。

備註

手機是描述語音音效的字母或符號。 System.Speech 支援三個語音字母來指定自訂發音：通用電話集 (UPS) 、語音 API (SAPI) 電話集，以及國際語音字母 (IPA) 。 中指定的 Pronunciation 手機必須符合 中指定的 PhoneticAlphabet 注音字母。 如需詳細資訊，請參閱 Lexicons 和注音字母 。

中指定的 Pronunciation 手機會指出 的內容應該如何 Text 發音，以便成功辨識。 語音辨識引擎會使用 中指定的 Pronunciation 發音來比對語音輸入，並傳回辨識結果中包含的字串 Text 。

如果手機不是以空格分隔，或指定的字串包含無法辨識的手機，辨識引擎就不會將指定的發音辨識為 包含 Text 之文字的有效發音。

中指定的 Pronunciation 發音優先于與文法或辨識引擎相關聯的語彙中所指定的發音。 此外，屬性中的 Pronunciation 發音只適用于 所 Text 包含單一出現的單字或片語。
