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.

Abstract: The distributed architecture switch of the invention provides a scalable, flexible switching device to route telephone calls and other data (e.g., frame relay, ISDN) over an asynchronous transfer mode (ATM) network. The switch includes multiple service modules that can be geographically disparate and function as a single switching device. The multiple service modules are coupled to a system controller that controls the service modules and passes messages between the service modules.
