Practical applications of voice input to machines

Voice input to machine is the most natural form of man-machine communications. In this type of system the machine responds to the mode of communications preferred by the user, rather than vice versa. Many practical applications exist today for limited capability voice input systems. The first operational voice input systems have taken place with limited vocabulary, isolated word voice input systems. Most of these initial systems were for industrial applications in which the users´ hands or eyes were already busy with their normal work requirements. Future developments in both new applications and increased capability voice input systems can be expected to considerably expand the usage of this form of man-machine communications.
