Abstract

A call between a caller using a telephone device for the deaf (TDD) using a one of a number of languages and another including a TDD user is connected by automatically prompting the TDD caller for calling information, automatically identifying the language being used, parsing the received calling information in the appropriate language to determine a forward number, selecting a communication assistant (CA) capable of speaking in the language routing the call to the selected CA, and connecting the call. One embodiment involves storing the forward number before routing the call so the selected CA can press a single button to connect the call. According to an embodiment of the invention, the calling information is passed directly to a number of language specific parsers and the successful parser determines the language being used.

Claims

1. A method of relaying a call between a telephone device for the deaf (TDD) and other users, comprising:

automatically notifying a TDD caller of readiness to receive calling information from a caller;

receiving caller entered prose calling information;

automatically analyzing the received prose calling information in a language-identifying parsing routine for parsing prose;

selecting a communication assistant capable of using a language identified in the analyzing step; and

automatically routing the call to the selected communication assistant.

2. The method as in claim 1, wherein the step of analyzing includes identifying the language the caller is using and then parsing the prose calling information in one of a plurality of language specific parsers.

3. The method as in claim 1, wherein the step of analyzing includes parsing the prose calling information in a plurality of language specific parsers and selecting a language from the successful one of said parsers.

4. The method as in claim 1, wherein the step of automatically notifying a TDD caller includes receiving the TDD call with a modem in a modem pool.

5. The method as in claim 1, wherein the step of routing the call to the selected communication assistant includes automatically determining whether a communication assistant capable in the identified language is available

6. The method as in claim 2, further comprising entering data into a billing record with at least one of a forwarding number, a billing number, a credit card number, and a calling number.

7. The method as in claim 3, further comprising entering data into a billing record with at least one of a forwarding number, a billing number, a credit card number, and a calling number.

8. The method as in claim 1, further comprising transferring an existing call already being handled by the selected communication assistant from the selected communication assistant when the existing call does not require use of the identified language.

9. The method as in claim 1, further comprising automatically dialing a forward number designated by the caller in the received prose calling information and prompting the communication assistant to handle the call.

10. A method as in claim 1, wherein the step of analyzing includes looking for a go ahead signal.

11. An apparatus for relaying a call between a telephone device for the deaf (TDD) and other users, comprising:

means for automatically prompting a TDD caller for calling information;

means for receiving caller entered prose calling information;

means for automatically analyzing the received prose calling information in a language-identifying parsing routine for parsing prose;

means for automatically selecting a communication assistant capable of using a language identified in the analyzing means; and

automatically routing the call to the selected communication assistant.

12. An apparatus as in claim 11, wherein the means for analyzing includes means for identifying the language the caller is using, a plurality of language specific parsers, and means for passing the calling information to the one of a plurality of language specific parsers that parses the prose of the identified language the caller is using.

13. An apparatus as in claim 11, wherein the means for analyzing includes a plurality of means for parsing the prose calling information each in one of a plurality of languages and selecting a language from the successful one of said parser means.

14. An apparatus as in claim 11, wherein the means for automatically notifying a TDD caller includes means for receiving the TDD call with a modem in a modem pool.

15. An apparatus as in claim 11, wherein the means for routing the call to the selected communication assistant includes means for automatically determining whether a communication assistant capable in the identified language is available. ahead signal.

16. An apparatus as in claim 11, wherein the means for analyzing includes means for looking for a go ahead signal.

17. An apparatus as in claim 11, further comprising means responsive to said received prose calling information for entering data into a billing record with at least one of a forwarding number, a billing number, a credit card number, and a calling number.

18. An apparatus as in claim 11, further comprising means for transferring an existing call already being handled by the selected communication assistant from the selected communication assistant when the existing call does not require use of the identified language.

19. An apparatus as in claim 11, further comprising means for automatically dialing a forward number designated by the caller in the received prose information and prompting the communication assistant to handle the call.
