There are so many ways to communicate with a deaf person in person. A person could learn how to sign which sounds easy, but it is not. You can trust me on that one. You have to use it or you will loose it.
Some deaf men and women have the ability to read lips. Lip reading is a good way to communicate with a deaf person; however, it is not the best way by any means. Lip reading is exhausting to a deaf person. It is a guessing game. They are doing their best to figure out what is being said. Some people think because a person has the ability to read lips that they should talk loud or try to enunciate the words to aid in communication. Let me tell you that it does not work. Speaking louder does not help because the person is deaf. They will not hear you all of a sudden. Enunciate the words or trying to speak slowly helps in distorting the word which adds to the communication issues in addition to making you look stupid. Always remember to speak in your normal voice when communicating with a lip reader. If the words you are trying to communicate are not coming across clearly then use other words that have the same meaning. It may be difficult for you to get your message across, but you are not doing half the work. It is even more challenging when the sole responsibility of translating, interrupting, and responding falls upon one person's shoulders. It is something to think about.
