Abstract: In a voice information system a telephone (1) is provided to transmit a Dual Tone Multi-Frequency (DTMF) signal by utilizing a character panel including a plurality of buttons (30) which are orderly arranged therein. An exchange (2) is provided to switch the DTMF signal. A telephone line matching apparatus (3) is connected from the exchange to detect a line status of the system and protect the system from an instantaneous higher voltage. A DTMF receiver apparatus (4) converts the DTMF signal into a corresponding digital signal. A service provider terminal means (9) is provided to input a plurality of key words corresponding to each service name and information data to be provided. A key word storage apparatus (6) includes a service name file unit for storing a service name file, and a key word dictionary unit for storing a key word dictionary. A text information storage apparatus (7) stores a plurality of information data corresponding to each service name. A Central Processor Unit converts a digital signal outputted from the DTMF receiver apparatus into an input character string to match the input character string with the key words stored in the key word storage apparatus in order to provide information data. A voice output apparatus is connected from the Central Processor Unit, for converting a digital voice data signal into a voice signal to thereby provide the desired information service to the user.

Abstract: A voice information system utilizing approximately matched input character string and key word and a method for the approximate matching thereof is disclosed. A telephone apparatus is provided to transmit a dual tone multi-frequency (DTMF) signal by utilizing a character panel including a plurality of buttons which are orderly arranged therein. An exchange apparatus is provided to intermediate the DTMF signal. A telephone line matching apparatus is connected from the exchange apparatus to detect a line status of the system and protect the system from an instantaneous higher voltage. A DTMF receiver apparatus converts the DTMF signal into a corresponding digital signal. A service provider terminal apparatus is provided to input a plurality of key words corresponding to each service name and information data to be provided.
