Abstract

A computer-based system (70) for identifying an unidentified caller (14) includes a database (42) that contains utterance data (162) corresponding to a known caller. A processing system (72) coupled to the database (42) receives utterance information corresponding to the unidentified caller (14) and compares the utterance information with the utterance data (162) to identify the unidentified caller (14) as the known caller. In response, the processing system (72) provides a call routing option (84). The call routing option (84) may include an accept option (86), a transfer option (90), or a disconnect option (89), and may be provided to a called party visually using a personal computer (50).

a control module coupled to the switching system and receiving the incoming call from the switching system, the control module further receiving the speech information from the switching system in response to the incoming call; and

a match module coupled to the control module and the database, the match module receiving speech data for the caller from the control module in response to the incoming call and independent of human interaction with the caller, the match module comparing the speech data for the caller with the stored speech data independent of human interaction with the caller to identify the caller, the system storing additional speech data identified with the known caller using the speech data for the caller, the control module providing a call routing option, in response to identification of the caller, for routing the incoming call.

2. The system of claim 1, wherein the database contains speech data corresponding to a plurality of known callers.

3. The system of claim 1, wherein the call routing option is selected from the group consisting of:

an accept option;

a transfer option; and

a disconnect option.

4. The system of claim 1, wherein the control module routes the incoming call according to a selected call routing option.

5. The system of claim 1, wherein the control module is further operable to receive a corrected identity for the caller in response to incorrectly identifying the caller as a particular known caller.

6. The system of claim 5, wherein the system is further operable to store the corrected identity for the caller in association with the speech data for the caller.

7. The system of claim 1, wherein the control module is further operable to provide the call routing option in response to selection of an accept option, wherein the call routing option is selected from the group consisting of:

a transfer option; and

a disconnect option.

8. The system of claim 1, wherein the control module is further operable to receive the identity of the caller if the caller is not identified independent of human interaction with the caller, the system being further operable to store the identity of the caller in association with the speech data for the caller.

21. The system of claim 1, wherein the match module compares speech data for a second caller with the stored speech data and with the additional stored speech data to identify the second caller.

9. A computer-based system for identifying a caller that performs the identification independent of human interaction with the caller, comprising:

a database that is integral to a computer and contains speech data identified with a known caller;

a switching system associated with a destination telephone number and receiving an incoming call and speech information from the caller, the caller having input the destination telephone number;

a control module integral to the computer and coupled to the switching system, the control module receiving the incoming call from the switching system and receiving the speech information from the switching system in response to the incoming call;

a match module, integral to the computer, coupled to the control module and to the database, the match module receiving speech data for the caller from the control module in response to the incoming call and independent of human interaction with the caller, the match module comparing the speech data for the caller with the stored speech data independent of human interaction with the caller to identify the caller, the control module providing a call routing option, in response to identification of the caller, for routing the incoming call; and

an output device coupled to the computer and operable to visually display the call routing option.

10. The system of claim 9, wherein the call routing option is selected from the group consisting of:

an accept option;

a transfer option; and

a disconnect option.

22. The system of claim 9, wherein the system stores additional speech data using the speech data for the caller and the match module compares speech data for a second caller with the stored speech data and with the additional stored speech data to identify the second caller.

11. A method for identifying an unidentified caller, the identification being performed independent of human interaction with the caller, the method comprising:

storing speech data identified with a known caller;

receiving an incoming call from the caller, the caller having input a destination telephone number;

receiving speech information from the caller in response to the incoming call;

communicating speech data for the caller to a match module independent of human interaction with the unidentified caller;

comparing the speech data for the caller with the stored speech data independent of human interaction with the caller and using the match module;

identifying the caller according to the comparison;

storing additional speech data identified with the known caller using the speech data for the caller; and

providing a call routing option, in response to identifying the caller, for routing the incoming call.

12. The method of claim 11, wherein the speech data for the known caller is stored in a database containing speech data corresponding to a plurality of known callers.

13. The method of claim 11, wherein the call routing option is selected from the group consisting of:

an accept option;

a transfer option; and

a disconnect option.

14. The method of claim 11, further comprising the steps of:

receiving a call routing option selection; and

routing the incoming call according to the selection.

15. The method of claim 11, further comprising the step of receiving a corrected identity for the caller in response to incorrectly identifying the caller as a particular known caller.

16. The method of claim 15, further comprising the step of storing the corrected identity in association with the speech data for the caller.

17. The method of claim 11, further comprising the step of:

receiving an accept option selection; and

wherein the step of providing the call routing option comprises providing the call routing option in response to receiving the selection, wherein the call routing option is selected from the group consisting of;

a transfer option; and

a disconnect option.

18. The method of claim 11, further comprising the steps of:

receiving the identity of the caller if the caller is not identified independent of human interaction with the caller; and

storing the identity of the caller in association with the speech data for the caller.

19. The method of claim 11, further comprising the step of comparing speech data for a second caller with the stored speech data and additional speech data, independent of human interaction with the second caller and using the match module, to identify the second caller.

20. The method of claim 11, wherein the step of providing the call routing option comprises providing the call routing option to a called party associated with the destination telephone number visually using a computer.

23. A computer-based system for identifying a caller and operable to perform the identification independent of human interaction with the caller, comprising:
