An interactive voice response system including a terminal and a center apparatus is disclosed. The terminal has a ten-key pad having a plurality of keys, which are so arranged as to emit lights in response to a control signal. The apparatus has a voice response program including one or more menus. The apparatus sends an audio guide for one of the menus to the terminal. The audio guide comprises audio option guides for menu options of the menu. The menu options and corresponding key IDs are extracted from the audio guide and sent to the terminal. Then, the menu options and the corresponding key IDs are displayed on a display device. The terminal also causes keys of the corresponding key IDs to emit lights. In response to an input of one of the keys, a signal associated with the key is sent to the apparatus.
