An advance in terms of speech synthesis aimed at patients with Cerebral Palsy and similar diseases has been developed by the University of Virginia. While in the past speech synthesis devices for the disabled have been somewhat erratic in operation and produced a harsh "metallic' voice, the research at the University of Virginia has improved on these. The new envisaged device is specifically designed "... To electronically reproduce sounds of the human voice and allow speech-impaired people to speak with fluidity and inflection" (Thomasson L.).
This device operates in relation to an individual's range of movement. These movements are 'tracked' on a computer by a programmer or a trained therapist and "...Once the movement, such as swinging the arm or wiggling the foot, is recorded, it is overlaid onto a sound grid. The vowel and consonant sounds are produced as the user moves a tracking device through the grid" (Thomasson L.). The device is also capable of producing any romance language, and will, according to...
The only negative aspect of this device is that it does require a fairly lengthy learning period in which the patient has to coordinate movement and the production of sounds. However the benefits of this device will mean that disabled people who in the past could not communicate can now interact and converse with others without any sense of embarrassment or loss of self-confidence.

Many of the answers used to hold workers with disabilities can also crack work-related problems of older workers. But older workers would not point out that they are disabled, even though they may come across functional limitations that are comparable to those met by persons with disabilities. Elder workers with vision, hearing, dexterity, memory, attention, standing, and/or sitting disabilities may come across difficulties on the job. There are a
Expert Systems and Neural Networks The Development and Limitations of Expert Systems and Neural Networks The human experience demands a constant series of decisions to survive in a hostile environment. The question of "fight or flight" and similar decisions has been translated into computer-based models by using the now-famous "if-then" programming command that has evolved into the promising field of artificial intelligence. In fact, in their groundbreaking work, Newell and Simon (1972)
You'd be able to hook up to the network through your computer, interactive TV, telephone, or some future device that somehow combines the attributes of all three. Even wireless gadgets such as pagers, future versions of cellular phones, and newfangled "personal digital assistants" would be able to tap into the highway. The purpose: to provide remote electronic banking, schooling, shopping, taxpaying, chatting, game playing, videoconferencing, movie ordering, medical diagnosing...
