According to this page, that is just not true.

When you read, your brain is working hard behind the scenes. It recognizes the shapes of letters, matches them to speech sounds, connects those sounds to meaning, then links those meanings across words, sentences and even whole books. The text uses visual structure such as punctuation marks, paragraph breaks or bolded words to guide understanding. You can go at your own speed.

Listening, on the other hand, requires your brain to work at the pace of the speaker. Because spoken language is fleeting, listeners must rely on cognitive processes, including memory to hold onto what they just heard.
