Some people with hearing impairment use lipreading to help them understand what others are saying.
Lipreading is very difficult. It is estimated that 70% of sounds look the same on the lips – for example:
- baby
- maybe, and
- pay me
...all look the same on your lips when you say them out loud.
Lipreading gives clues to augment existing hearing, but it cannot be used alone for unambiguous communication, and it requires a great deal of concentration. It can be very exhausting.
