How do hearing-impaired people talk?

Hearing-impaired cannot hear sound well. How do they “hear” word and talk? Maybe hearing-impaired people use American Sign Language (ASL). They talk with their hands. Sometime two hearing-impaired talk to each other. They both use ASL. Sometime a person who can hear interprets for hearing-impaired people. The person listens to someone talking, and then he or she makes hand signs. There are two kinds of sign language. One kind has a sign for every letter in the alphabet. The person spells words. This is finger spelling. The other kind has a sign for whole words. There are about five thousand (5,000) of these signs. They are signs for verbs, things, and ideas. Some of the signs are very easy, for example, eat, milk, and house. You can see what they mean. Other are more difficult, for example, star, egg, or week. People form any country can learn ASL. They don’t speak word. They use sign, so they can understand people from other countries. ASL is almost like a dance. They whole body talk. American Sign Language is a beautiful language.
