Google Read Aloud user agent
Google-Read-Aloud is the user agent for the Google Read Aloud service. This service enables
reading web pages using text-to-speech (TTS). This service is activated when an end user has
TTS enabled and visits a page. The Read Aloud service is used by
Google Read it,
Read Aloud on the Google app, and other Google text-to-speech services.
Crawl frequency and behavior
Google Read Aloud is triggered by a user request. Google Read Aloud conserves bandwidth by caching page results, but you may still see multiple requests for a given page.
Google Read Aloud is not a web crawler: it is activated upon user request, and it doesn't follow links. A user request for listening to a web page may or may not result in page visits, depending on whether the page has been fetched recently.

Since Google Read Aloud is initiated by a user, not a result of automated web crawl, you can't opt out
by using a robots.txt file. To opt out of Google Read Aloud completely, use the
nopagereadaloud meta tag:
<meta name="google" content="nopagereadaloud">
