There are a wide range of hearing losses and communication preferences. If you do not know the individual's preferred communication method, ask. Address questions, comments, or concerns directly to the individual, not to a person in their presence. Shouting or exaggerating one's speech does not help communication. If you do not understand what is being said, do not pretend to understand.
Interpreters are present to relay information.
They generally should not be included in the conversation. Make direct eye contact. Natural facial expressions and gestures will provide important information to your conversation. Keep your face and mouth visible by not obscuring with your hands, hair, cigarettes and food. When speaking to a person who lip-reads, speak clearly and evenly.
