Interpreting lip movements is a skill that requires a person to be able to understand and interpret the subtle movements of another person's lips. This skill is often used by people who are deaf or hard of hearing, as well as those who are learning a new language. It is also used in the field of speech-language pathology, where it can help diagnose and treat speech and language disorders. The term 'reads' is a five-letter word that can be used to describe this skill, as it implies that the person is able to accurately interpret the movements of another person's lips.
