One of the important problems that our society faces is that people with disabilities are finding it hard to cope up with the fast growing technology. In the recent years, there has been a rapid increase in the number of hearing impaired and speech disabled victims due to birth defects, oral diseases and accidents. When a deaf-dumb person speaks to a normal person, the normal person seldom understands and asks the deaf-dumb person to show gestures for his/her needs. Dumb persons have their own language to communicate to us; the only thing is that we need to understand their language. So, we need a translator to understand what they speak and communicate to us. In order to achieve this, we have proposed a system that can provide basic communication needs for a deaf-dumb person and also aid him in many ways. In the proposed system, we have used a speech recognition unit along with audio pre recorder and embedded controllers which will be helpful for deaf and dumb persons to express their needs to normal person. The frequently spoken words are stored in audio pre recorder which can be easily retrieved and also displayed using Liquid Crystal Display. The proposed device is also helpful for born deaf children to learn the basics of any language. In addition, voice based home automation system is also proposed for elderly and disabled people. Home automation system is achieved by wireless RF transmission and reception techniques integrated with our Embedded Voice Translator Kit. The proposed system along with text to speech converter and language translators as future enhancements will provide great assistance to deaf and dumb persons to portray their needs to society. Our system can also be incorporated for various applications like personal security, wireless TV remote control etc.
