Presently, the universal remote controller and voice-controlled means are the most convenient ways in controlling the functions of various audio-video equipments. The conventional universal remote controller is used to execute the remote-control functions through the setting of the audio-video equipment. However, the surface area of the universal remote controller has too many keys to provide convenient and efficient operation. In order to contain so many keys in such a limited area, the size of the respective keys is reduced to the minimum, thus making their operation even more inconvenient.
In the conventional voice control function, the voice instructions are used to control the operations of the various audio-video equipments. Usually, users are required to follow specific rules or routes to execute different operations. In addition, in terminating operations currently executed, such specific rules or routes must be followed, thus the operation procedure is complicated and evidently not convenient for users.
