Abstract

A speech conversion system facilitates voice communications. A database comprises a plurality of conversion heuristics, at least some of the conversion heuristics being associated with identification information for at least one first party. At least one speech converter is configured to convert a first speech signal received from the at least one first party into a converted first speech signal different than the first speech signal.

Claims

1. A system comprising:

a database comprising a plurality of conversion heuristics, at least one of the plurality of conversion heuristics being associated with identification information about a first party determined from a first speech signal received from the first party;

at least one speech converter configured to convert, according to the at least one conversion heuristic associated with the identification information for the first party, the first speech signal received from the first party into a converted first speech signal different than the first speech signal; and

at least one conversion server configured to communicate with the at least one speech converter, the at least one conversion server configured to determine the identification information about the first party from the first speech signal and retrieve the at least one conversion heuristic based at least in part on the identification information determined about the first party,

wherein at least one of the database and the at least one speech converter is at least partially implemented using a hardware device.

2. The system of claim 1, further comprising at least one conversion server configured to communicate with the at least one speech converter.

3. The system of claim 1, further comprising at least one converter selection interface configured to allow the first party to manually provide additional identification information.

4. The system of claim 3, wherein the at least one speech converter is further configured to transmit the converted first speech signal to a second party different than the first party, and wherein the at least one converter selection interface is configured to allow the second party to manually select the at least one conversion heuristic.

5. The system of claim 1, wherein two or more conversion heuristics are used for converting the first speech signal to the converted first speech signal.

6. The system of claim 1, wherein the identification information used to select the at least one conversion heuristic includes at least one of a geographic location, an area code, a telephone number, an Internet Protocol (IP) address, a gender, a classification of a speech accent, and a classification of a speech impairment.

7. The system of claim 1, wherein the at least one speech converter is selected to perform at least one of a gender translation, an accent translation, a language translation, a speech tone translation, and a speech enhancement.

8. A system comprising:

a database comprising a plurality of conversion heuristics; and

at least one speech converter configured to convert a first speech signal received from a first party into a converted first speech signal according to at least one first party conversion heuristic retrieved from the database based on identification information about a first party determined from the first speech signal from the first party, and transmit the converted first speech signal to at least one second party different than the first party; and

wherein said at least one speech converter is further configured to convert at least one second speech signal received from the at least one second party into a respective at least one converted second speech signal according to at least one second party conversion heuristic retrieved from the database based on identification information determined from the at least one second speech signal about the at least one second party, and transmit the at least one converted second speech signal to the first party;

at least one conversion server configured to communicate with the at least one speech converter, the at least one conversion server configured to determine the identification information about at least one of the first party from the first speech signal and the at least one second party from the at least one second speech signal and retrieve at least one of the at least one first party conversion heuristic and the second party conversion heuristic, such retrieval based at least in part on the identification information determined about the first party from the first signal or the identification information determined about the at least one second party from the at least one second signal, respectively,

wherein at least one of the database and the at least one speech converter is at least partially implemented using a hardware device.

9. The system of claim 8, further comprising at least one converter selection interface configured to allow the at least one first party conversion heuristic or the at least one second party conversion heuristic to be manually selected.

10. The system of claim 8, wherein two or more conversion heuristics are used for converting the first speech signal.

11. The system of claim 8, wherein two or more conversion heuristics are used for converting the at least one second speech signal.

12. The system of claim 8, wherein the identification information used to select the at least one conversion heuristic includes at least one of a geographic location, an area code, a telephone number, an Internet Protocol (IP) address, a gender, a classification of a speech accent, and a classification of a speech impairment.

13. The system of claim 8, wherein the at least one speech converter is selected to perform at least one of a gender translation, an accent translation, a language translation, a speech tone translation, and a speech enhancement.

14. A method comprising:

receiving a first speech signal;

determining identification information about a party based on the received speech signal using a conversion server;

selecting at least one conversion heuristic from a database based on the identification information, wherein the database is at least partially implemented using a hardware device; and

converting the first speech signal to a second speech signal according to the at least one conversion heuristic.

15. The method of claim 14, wherein the identification information used to select the at least one conversion heuristic includes at least one of a geographic location, an area code, a telephone number, an Internet Protocol (IP) address, a gender, a classification of a speech accent, and a classification of a speech impairment.

16. The method of claim 15, further comprising receiving input from a speech converter interface, wherein the selecting step uses the input to select the at least one conversion heuristic.

17. The method of claim 15, wherein the converting step includes at least one of a gender translation, an accent translation, a language translation, a speech tone translation, and a speech enhancement.
