When you read, you probably hear the words in your head, like someone is reading them to you – this is called subvocalization.
Subvocalization is a natural process that helps us understand and remember what we read, acting like a mental storage system for words.
Scientists believe that subvocalization helps us connect words together to make sense of a sentence and can even improve reading comprehension.
Although some people try to stop their inner voice to read faster, subvocalization is actually a helpful tool for making the most of what we read.
