Abstract

A speech recognition-based channel selecting apparatus is provided wherein an operator can easily select a channel, only as he or she pronounces a display channel, a receive channel or the name or the like of a broadcasting station matching with a location that he or she lives, without cumbersome registration of words. The channel selecting apparatus according to the present invention comprises: a table containing units of language which represent receive channels; a channel setting information storing unit which stores channel selecting positions and receive channels in mutual correlation with each other; a dictionary containing registrations of units of language which represent receive channels correlated with channel selecting positions; a dictionary generating unit which, when a new receive channel is correlated with a channel selecting position, automatically searches for a unit of language which represents the receive channel newly correlated with that channel selecting position from the table, then registers a searched word in the dictionary and accordingly updates the dictionary; a speech inputting unit; a speech recognition unit; and a channel selection controlling unit which receives a signal for the receive channel and outputs the signal based on the recognition result.
