The Media Resource Control Protocol (MRCP) Version 2 (MRCP v2) feature provides support for 
MRCP v2 for use with specified Cisco IOS voice gateways' VoiceXML Browser. The MRCP v2 protocol 
allows a client device to control media processing resources on the network. Media processing resources 
include speech recognition engines, speech synthesis engines, speaker verification and speaker 
identification engines. MRCP v2 enables the implementation of distributed Interactive Voice Response 
(IVR) platforms using VoiceXML browsers or other client applications while maintaining separate 
back-end speech processing capabilities on specialized speech processing servers. MRCP v2 is based on 
the earlier MRCP developed by Cisco Systems, Inc., Nuance Communications, Inc. and Speechworks, 
Inc.
