recording of sound are turned into digital data, then permanently stored on disc or in a memory chip. When this is converted back into output the data also reverts to analog and is then sent to a speaker.This technique of data control can be beneficial to business in creating mass production applications such as automatic teller machines, smoke detectors, vehicle warning systems and vending machines to mention a few. When the sounds are stored on disc, it gives the user the flexibility to alter and update the sounds keep up and meet changing application needs.Speech synthesis systems, on the other hand, covert raw data into electronically produced speech. This variety of voice response system tends to be more popular within the microcomputer environment. All you need to produce speech on a PC are a sound expansion board, speakers and the necessary software. This produces synthesised speech and can be used to help a visually impaired person to translate printed words into spoken words.Translation systems offer one of the most beneficial applications of voice response systems to the business world. It enables conversations to occur among people who are speaking different languages. The process can deal with people from three different countries to carry on a computer aided conversation thus enabling businesses to communicate more readily and freely to save time and maximise its sales processing. Telephone terminals and telephony:The telephones wide spread availability lends itself to a new and useful form of ICT processing in the form of a terminal. You can enter alphanumeric data on the touch tone keypad of a telephone or by speaking into the receiver (voice input). You are then able to receive computer-generated output from a voice response system. Sales people use telephones as terminals on a daily basis to improve communications. It enables them to enter orders and enquires about certain products availability via their mainframe compu...
