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 providing audible caller information, the method comprising:

receiving a call from a caller to a called party;

searching a caller information database for caller information of the caller;

receiving the caller information of the caller from the caller information database, wherein the caller information is in a form unsuitable for text-to-speech synthesis;

converting the caller information to a form that is suitable for text-to-speech synthesis;

establishing the call between the caller and the called party; and

performing text-to-speech synthesis of the converted caller information.

2. The method of claim 1, wherein the caller information is converted 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.

3. The method of claim 2 further comprising determining whether the caller information contains a residential or business listing.

4. 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.

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

6. The method of claim 1, wherein the caller information is converted to a form that is suitable for text-to-speech synthesis by removing at least one irregular character from the caller information.

7. A telecommunication system comprising:

a caller information database comprising caller information of a plurality of parties;

a service node operative to;

retrieve, from the caller information database, caller information of a caller making a call to a called party and convert the caller information to a form that is suitable for text-to-speech synthesis; and

at least one component operative to establish the call between the caller and the called party.

8. The system of claim 7, wherein the service node comprises an intelligent peripheral.

9. The system of claim 7, wherein the service node comprises a pre-processor and a text-to-speech synthesizer.

10. The system of claim 7, wherein the service node converts the caller information 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.

11. The system of claim 10, wherein the service node is operative to determine whether the caller information contains a residential or business listing.

12. The system of claim 7, 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.

13. The system of claim 7, wherein the service node is operative to compare the caller information to a state name table.

14. The system of claim 7, wherein the service node converts the caller information by removing at least one irregular character from the caller information.

15. The system of claim 7, wherein the service node is further operative to perform text-to-speech synthesis of the converted caller information.

16. A computer-usable memory storing at least one computer program, the at least one computer program operative to retrieve, from a caller information database, caller information of a caller making a call to a called party, convert the caller information to a form that is suitable for text-to-speech synthesis, and establish the call between the caller and the called party.

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

18. The computer-usable memory of claim 17, wherein the service node comprises an intelligent peripheral.

19. The computer-usable memory of claim 16, wherein the caller information is converted by removing at least one irregular character from the caller information.

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