Silent reading is actually a shockingly recent invention. Because the letters “make sounds”, the natural way to process a phonetic alphabet is to make the sounds of the letters as you read them and listen to yourself speaking the text. This goes on way later than many people realize. Being able to do silent reading at all was still a pretty remarkable skill in the time of Shakespeare. Being unable to read something without speaking the words was common probably well into the 19th century. Actually, as someone who works in education I can tell you that I will still recommend kids to read things out loud if they find something difficult. It’s what phonetic writing languages were designed for, and it increases accuracy and comprehension.
