They do not acquire spoken language as hearing children do.About one in thousand babies is born deaf with a severe hearing deficiency. It’s nearly impossible to learn spoken language by hearing for deaf children. Normal speech depends large on auditory feed back. Deaf persons can be taught to speak a language by reading the lips of others. But 75% of spoken English words can not be read on the lips accurately.
