ADVANTAGES
Advances in technology will allow consumers and businesses to implement speech recognition systems at a relatively low cost. Cell-phone users can dial pre-programmed numbers by voice command. Users can trade stocks through a voice-activated trading system. Speech recognition technology can also replace touch-tone dialing resulting in the ability
to target customers that speak different languages. Disabilities person easy handling.
