Abstract

A network based processing element for processing audio information improves the understanding of speech or music for intended listeners based on an identifier. The processing involves performing a media enhancement function, where a parameter affecting the utilization or performance aspects of the media enhancement function are dependent upon the identifier. A “media enhancement server” (MES) is included, whereby the audio of a telephone call, video call, multimedia program or other stream to be heard by a specific listener is processed using a personalized audio enhancement parameter to enhance the audio signal such that the listener will enjoy a benefit, such as better comprehension of the information, reduced listening effort, and more listening comfort during the call. The personalized parameters are stored and retrieved based upon the identifier, and used within the MES. The audio portion of the call or stream could be speech, music, or a combination.

Claims

1. A system for improving perceived audio quality in a communications network comprising a provisioning server for routing audio from and to a user, the system comprising:

a signal processor;

a communication device connected to said communication network, wherein the communication device is associated with a user;

an identifier received by said signal processor, wherein the identifier is associated with the user, wherein the identifier comprises at least one of a user name and a personal identification number (PIN), and wherein the identifier allows for improving perceived audio quality for the user on a plurality of devices;

a transmitter for transmitting audio signals to said communication device, wherein the audio signals are transmitted as part of a hearing test;

a receiver for receiving responses to said audio signal from said communication device;

a comparator in said signal processor for determining the error between the audio signal transmitted from said signal processor to said communication device and the response audio signal; and

a logic control generator for;

identifying at least one personalized parameter to be applied to subsequent audio signals transferred to said communication device, wherein the at least one personalized parameter is personalized for the user;

determining a type of the subsequent audio signals; and

based upon the type of the subsequent audio signals, modifying the subsequent audio signals signal provided to said media device using said personalized parameter.

2. The system of claim 1, wherein said identifier comprises at least one of a Mobile Identity number (MIN), an IMSI, a TMSI, a phone number, a SIP URL, a MAC address, a user name, a user selection, an account number, an IP address, a device address, a device serial number, a caller identification, an identity indication, a virtual connection (VC), a connection identifier, a CID, a CNID, and a line identification.

3. The system of claim 1, wherein said logic control generator is adapted to select a first personalized parameter for altering a voice signal, said first personalized parameter including at least one of an automatic gain control, an audio gain control, an equalization, and an energy redistribution.

4. The system of claim 1, wherein said transmitter, said receiver, said comparator, and said logic control generator are physically located in the provisioning server.

5. The system of claim 4, wherein said personalized parameter is transferred from said provisioning server to a media enhancement server and is applied to a subsequent audio signal by said media enhancement server.

6. The system of claim 5, wherein said media enhancement server is located discrete from said provisioning server.

7. The system of claim 1, wherein said logic control generator is adapted to generate the at least one personalized parameter in a first optimization step, and wherein the system further comprises a media enhancement server adapted to apply said personalized parameter to voice signals in a temporally different step.

8. The system of claim 7, wherein the provisioning server is adapted to receive a first telephone call and the media enhancement server is adapted to receive at least one subsequent telephone call and forward automatically the at least one subsequent telephone call to a third party.

9. The system of claim 7, wherein the provisioning server is adapted to receive a first telephone call from the user and the media enhancement server is adapted to receive at least one subsequent telephone call from a third party and forward automatically the at least one subsequent telephone call to the user.

10. The system of claim 7, wherein the provisioning server is adapted to initiate a first telephone call to the user and the media enhancement server is adapted to receive at least one subsequent telephone call from the user and forward automatically the at least one subsequent telephone call to a third party.

11. The system of claim 5, wherein said media enhancement server is adapted to store the at least one personalized parameter.

12. The system of claim 1, wherein said receiver is adapted to receive keyed information from an operator, wherein the operated records responses to said audio signals.

13. In a media communication network, a method for improving the quality of media content, the method comprising:

identifying a user with an identifier, wherein the identifier comprises at least one of a user name and a personal identification number (PIN), and wherein the identifier allows for improving perceived audio quality for the user on a plurality of devices;

transmitting a media signal to the user of said media device, wherein the media signal is transmitted as part of a hearing test;

receiving a response signal from said user;

comparing said transmitted media signal and said response signal to determine an error between said transmitted media signal and said response signal;

determining at least one personalized parameter, wherein the at least one personalized parameter is personalized for the user based on the error;

determining a type of a subsequent media signal; and

based upon the type of the subsequent media signal, modifying the subsequent media signal provided to said media device using said personalized parameter.

14. The method of claim 13, wherein said transmitted media signal and said response signal each comprise audio signals.

15. The method of claim 13, further comprising selectively applying said personalized parameter to a second subsequent media signal.

16. The method of claim 13, comprising applying the personalized parameter to a second media device based on a selection by the user.

17. The method of claim 13, further comprising applying, by a media enhancement server, said at least one personalized parameter to a second subsequent media signal in said communication network.

18. The method of claim 13, further comprising applying, by said media device, said at least one personalized parameter to a second subsequent media signal in said communication network.

19. A mass-storage device encoding computer executable instructions that, when executed by at least one processor, perform a method for improving the quality of media content, the method comprising:

identifying a user with an identifier, wherein the identifier comprises at least one of a user name, a personal identification number (PIN), and voice recognition, and wherein the identifier allows for improving perceived audio quality for the user on a plurality of devices;

transmitting a media signal to the user of said media device, wherein the media signal is transmitted as part of a hearing test;

receiving a response signal from said user;

comparing said transmitted media signal and said response signal to determine an error between said transmitted media signal and said response signal;

determining at least one personalized parameter, wherein the at least one personalized parameter is personalized for the user based on the error;

determining a type of a subsequent media signal; and

based upon the type of the subsequent media signal, modifying the subsequent media signal provided to said media device using said personalized parameter.

20. The mass-storage device of claim 19, wherein the method further comprises applying the personalized parameter to a second media device based on a selection by the user.
