What it is used for
Per Google, upon user request Google Read Aloud fetches and reads out web pages using text-to-speech (TTS). Its former user agent, google-speakr, is deprecated.
Not the crawler behind a search index. What blocking it changes is specific to its tool, so read the next section.
What happens if you block it
Per Google, user-triggered fetchers generally ignore robots.txt, so a robots.txt rule may not stop a page from being read aloud on request.
Google documents a desktop and a mobile user agent; both contain Google-Read-Aloud. The mobile one starts with an Android Chrome string.
Is it really Google-Read-Aloud?
Anyone can send Google-Read-Aloud as a user agent, so a log line proves nothing by itself. The way to tell is the requesting IP address.
- Compare the IP address with the Google: Verify Google requests (links the user-triggered fetcher IP files). A request from outside those ranges is not the operator's crawler.
- Google documents reverse DNS names of the form ***-***-***-***.gae.googleusercontent.com (Google-owned fetchers) or google-proxy-***-***-***-***.google.com (user-owned fetchers) for its user-triggered fetchers, to be confirmed by a forward lookup.
