* 若要讓指定的語音合成器使用不同的已安裝語音，請呼叫 [XSpeechSynthesizerSetCustomVoice](/zh-TW/reference/system/xspeechsynthesizer/functions/xspeechsynthesizersetcustomvoice)。

* 若要列舉並取得目前裝置上所安裝之語音的相關資訊，請搭配使用 [XSpeechSynthesizerEnumerateInstalledVoices](/zh-TW/reference/system/xspeechsynthesizer/functions/xspeechsynthesizerenumerateinstalledvoices) 函式與 [XSpeechSynthesizerInstalledVoicesCallback](/zh-TW/reference/system/xspeechsynthesizer/functions/xspeechsynthesizerinstalledvoicescallback) 回呼函式。

* 對於每個已安裝的語音，[XSpeechSynthesizerVoiceInformation](/zh-TW/reference/system/xspeechsynthesizer/structs/xspeechsynthesizervoiceinformation) 結構會提供語音識別碼、描述、顯示文字、性別、語言及其他資訊。
