If the input from the user does not wish to register (S36, N), the flow of the communication terminal 50 ends.

Next, in the server 60, when the personal information of the caller input by the user is received from the communication terminal 50 (S47, Y), the control unit 63 transmits the voiceprint information of the caller and the personal information of the caller. Are linked and stored in the database of the storage unit 65 (S48), and the flow of the server 60 ends. If the signal processing unit 61 does not receive the personal information of the caller input by the user from the communication terminal 50 (S47, N), the flow of the server 60 ends.

According to the processing described above, at the start of a call due to an incoming call, the user can identify the caller by visually recognizing the personal information displayed on the LCD 17. If the voiceprint information of the caller is not stored in the database of the server 60, the user inputs the personal information of the caller and transmits the information from the communication terminal 50, and the voiceprint information of the caller is stored in the database of the server 60. And personal information can be linked and saved. In the present embodiment, the server 60, which has higher computational performance than the communication terminal 50, performs voiceprint analysis and comparison, so that an individual can be identified at high speed. Since it is not necessary to provide the communication terminal 50, the circuit scale of the communication terminal 50 can be reduced.

It should be noted that the first embodiment is in force! /, And, using a communication terminal that performs wireless communication as an example, As described above, the present invention can be applied to a communication terminal that performs wired communication. In addition, although the visual display using the LCD as the display unit has been described, it is also possible to perform audio display or the like. As described above, Embodiments 1 to 3 have been described. However, the configurations and operations of the communication terminals and the servers described in the above-described embodiments are examples for realizing the present invention, and the configuration is based on the gist of the present invention. It is needless to say that the present invention is not particularly limited as long as it does not deviate from the above, and can be appropriately applied. Industrial potential

As described above, according to the present invention, at the start of a call due to an incoming call, by visually recognizing the personal information of the caller displayed on the screen, the user can accurately specify the individual caller. For example, it is possible to avoid misleading the caller and causing trouble for the other party.
