Abstract: When the number of characters displayable on a character display area of a display is restricted, the information providing system generates a first recognition object word from information of object to be provided. At the same time, the information providing system generates a second recognition object word by using whole of a character string which is obtained by shortening the first recognition object word to have the specified character number when its number of characters exceeds a specified character number, to thereby recognize a speech voice by a user, using the first recognition object word and the second recognition object word.
