Google 朗讀使用者代理程式
Google-Read-Aloud 是 Google 朗讀服務的使用者代理程式。這項服務可讓系統透過文字轉語音 (TTS) 程序朗讀網頁內容，如果使用者在啟用 TTS 的情況下造訪網頁，系統就會啟用這項服務。會使用大聲朗讀的服務包括 Google Go、Google Read it、Google 應用程式中的大聲朗讀功能以及其他 Google 文字轉語音服務。
檢索頻率和行為
Google 朗讀是由使用者提出要求所觸發。Google 朗讀會快取網頁結果以節省頻寬，不過您可能還是會看到單一網頁收到多次要求。
Google 朗讀服務不是網路檢索器，只會在使用者要求朗讀時執行，且不會追蹤連結。使用者提出聆聽網頁內容的要求後，系統會根據近期是否曾擷取該網頁內容，判斷是否需要造訪網頁。
禁止 Google 朗讀服務存取您的內容
由於 Google 朗讀服務啟動的依據是使用者的要求，而不是自動網路檢索作業的結果，因此您無法藉由 robots.txt 檔案加以停用。如要完全停用 Google 朗讀，請使用 nopagereadaloud meta 標記，如下所示：
<meta name="google" content="nopagereadaloud">
如要避免系統朗讀付費牆內容，請為訂閱和付費牆內容使用結構化資料，並確認 isAccessibleForFree 屬性已設為 False。
