Abstract
The present invention addresses the need for an apparatus and method for facilitating and performing distributed speech processing in a wireless communication system. The present invention encompasses communication infrastructure embodiments that facilitate distributed speech processing by establishing voice and data pathways to support distributed speech processing services. The present invention also encompasses a communication unit that performs distributed voice recognition and distributed speech synthesis via the communication infrastructure. The communication unit (102) requests communication services from the communication infrastructure (101) that support both voice and data communication and utilizes a data connection to a distributed speech processing unit (116) to perform distributed voice recognition and distributed speech synthesis.
