ABSTRACT:
A method and device for inputting characters. An answering equipment, Ts, answers a call from a terminal equipment, Te. The answering equipment transmits a sequence of characters which can consist of letters, digits or other characters. The information is transmitted via the telecommunications network to the terminal equipment where the information is read out in a loudspeaker which is listened to by a subscriber. When the subscriber hears the character in question being read, he/she presses a key on the terminal equipment. The key can be one of the keys on the ordinary keypad of twelve keys on the telephone. The signal passes to the answering equipment where it is identified and registers that the character in question shall be stored in a data base, DB. The data base stores the character and combines the other characters which are input, and predicts which possible words or character combinations remain, depending on application. When the number of possible combinations is lower than a predetermined number, the system changes to read out current character combinations or words. The subscriber confirms which characters or character combinations or words are intended. When a word or a character combination has been completely identified, this is used for transmitting the information to the subscriber. The current information can for instance refer to the owner of a car with a certain car number, or the telephone number of a wanted person etc.
