Hi Geoff Page,
Thank you for reaching out to us on the Microsoft Q&A forum.
The "Read Aloud" feature is not available directly within the Learning Paths or Modules themselves. However, you can still utilize the "Read aloud this page" option, which can be found next to the URL in your browser, as demonstrated in the attached screenshot. This option will allow you to have the content of the page read aloud to you, even if it's not natively built into the modules.
If you found the information helpful, we would greatly appreciate it if you could acknowledge it by selecting the Accept Answer & Upvote options.
