Filed: 1999-05-13
Abstract: PROBLEM TO BE SOLVED: To accurately know an originator individual and to enable a receiving subscriber to know his originating opposite party to select whether or not an answer should be given to a relevant call by transmitting the personal data which match with the data having matching voice prints to the opposite party of communication. SOLUTION: A telephone transmitter of an originating terminal 1 collects the voices of talking persons and sends them to a voiceprint analysis/collation device 3 as voiceprint data via a voice print recognizing unit 2. Meanwhile, the voice print data and their corresponding personal data including the names, etc., are stored previously in a voiceprint data base 4. Then the device 3 collates its received voiceprint data with those stored in the data base 4 and analyzes them to send the personal data to a receiving terminal 5 when the matching is confirmed between both voice print data. If no matching is confirmed between both voice print data, a message is sent to the receisrng terminal 5 to the effect that the talking persons are unknown. Thus, an originator is prescribed according to matching or non-matching of voice prints and then notified to a receiving subscriber.  As a result, the receiving subscriber is able to know the originator, even for a call that is received from a public telephone set, etc., to which the originating telephone number is not notified.
