Communication systems for people with severe hearing loss

Automatic speech recognition has long been an object of studies, as it is based on the idea of the dialog between man and computer. The first work on speech recognition was published in 1952, and it described a system created by the Bell Laboratory. Many people with severe hearing loss rely on sign language as the main means of communication, yet, in time, advanced research in the field has lead to the human communication with the computer, albeit with some limitations. Nowadays, communication with the computer may be done by using a speech recognition system and a voice synthesis system.
