Does reading improve one’s vocabulary and lessen the use of filler words? Also is it possible to improve this as an adult? /u/CardiologistThen4916 No such thing as stupid questions

I really want to improve my vocabulary and not use filler words. For instance the words “like and um”. What are some good books to read that can help me out?
