Deaf and dumb people many not be able to hear or speak, but that does not mean that they cannot communicate with others. Instead of talking as we do, they talk with their fingers and hands. We can also say that they communicate through a visual language. There are two kinds of deaf and dumb sign language. One method uses one hand, the other uses both hands. Different finger positions stand for different letters of the alphabet, and words are spelt out one letter at a time.Signs used by the deaf and dumb also represent ideas. Many signs use a visual image to convey an idea. For example, mimicking a pair of horns means a deer, or a trunk means an elephant.Sometimes, deaf and dumb people use facial expressions and other gestures in order to communicate faster. Nowadays, there are many techniques that teach deaf people to speak like we do. They also learn to read lips so that they can understand.
