Don’t assume that every deaf person speechreads. Speechreading is a very difficult skill to master, and many deaf people don’t find it effective beyond common phrases such as “How are you?”
Keep your face and lips visible.
Maintain eye contact.
Make sure the deaf person is looking at you before you speak, sign, or gesture.
Speak naturally. Don’t exaggerate your mouth movements or speak too slowly. And don’t shout!
Be careful not to stand with your back to a window or other light source – this makes speechreading and getting information from facial expressions difficult.
Offer pen and paper to write notes back and forth, but be aware that English is a second language for many deaf people. When writing notes, use short sentences and plain language, and avoid idioms and slang.
Repeat the question to make sure you understand.
To get the attention of the deaf person, tap his or her shoulder or arm or wave in his or her line of sight.
ATTITUDE is the most important thing! Most deaf people will appreciate your efforts to communicate.
