Abstract

A system (10) and method (40) for providing audible caller information to telephone service subscribers is presented. The system (10) includes a pre-processor (28) that converts textual caller information from a first data format to a second data format suitable for text-to-speech synthesis (TTS). The pre-processor (28) can be incorporated in a service node/intelligent peripheral (SN/IP) (24) in an advanced intelligent network (AIN). In this configuration, the pre-processor (28) can be used to convert caller-ID with name database entries into a predetermined TTS format. The TTS formatted information can be provided to a TTS synthesized (30) included in the SN/IP (24). In conjunction with a switching service point (SSP) (20), the pre-processor (28) can provide a talking call-waiting feature to subscribers with significantly improved intelligibility.

Claims

1. A method for removing an irregular character from caller information, the method comprising:

receiving caller information; and

removing at least one irregular character from the caller information.

2. The method of claim 1 further comprising performing text-to-speech synthesis of the caller information after the at least one irregular character has been removed.

3. The method of claim 1, wherein the received caller information is in a first format, and wherein the method further comprises converting the caller information from the first format to a second format.

4. The method of claim 3, wherein the conversion from the first format to the second format is in accordance with a set of rules comprising a first subset of rules for business listings and a second subset of rules for residential listings.

5. The method of claim 4 further comprising determining whether the caller information contains a residential or business listing.

6. The method of claim 1 further comprising comparing the caller information to an exceptions table and, if the caller information corresponds to an entry in the exceptions table, generating a predetermined output.

7. The method of claim 1 further comprising comparing the caller information to a state name table.

8. A telecommunication system comprising:

a service node operative to remove at least one irregular character from caller information.

9. The system of claim 8, wherein the service node comprises an intelligent peripheral.

10. The system of claim 8, wherein the service node comprises a pre-processor and a text-to-speech synthesizer.

11. The system of claim 8, wherein the caller information is in a first format, and wherein the service node is operative to convert the caller information from the first format to a second format.

12. The system of claim 11, wherein the conversion from the first format to the second format is in accordance with a set of rules comprising a first subset of rules for business listings and a second subset of rules for residential listings.

13. The system of claim 12, wherein the service node is operative to determine whether the caller information contains a residential or business listing.

14. The system of claim 8, wherein the service node is operative to compare the caller information to an exceptions table and, if the caller information corresponds to an entry in the exceptions table, generate a predetermined output.

15. The system of claim 8, wherein the service node is operative to compare the caller information to a state name table.

16. A computer-usable memory storing at least one computer program, the at least one computer program operative to remove at least one irregular character from caller information.

17. The invention of claim 16, wherein the computer-usable memory is part of a service node.

18. The invention of claim 17, wherein the service node comprises an intelligent peripheral.

19. The invention of claim 16, wherein the caller information is in a first format, and wherein the at least one computer program is operative to convert the caller information from the first format to a second format.

20. The invention of claim 16, wherein the at least one computer program is operative to communicate with a service switching point.
