University sites generally identify each page's language as English.
This means screen readers will pronounce all text on the page as if it was written in English. For non-English text, the result is unintelligible gibberish.
If you are authoring content inside of a page that is a language other than English you will have to identify the language of that section or quote. Most content management systems provide a button for this; highlight the relevant content, click the button, and select the correct language from the list:
