About MRCP

The Media Resource Control Protocol (MRCP) is an Internet Engineering Task Force (IETF) specification that describes a standard interface for media processing resources providing capabilities such as automatic speech recognition (ASR), speech synthesis (text to speech or TTS), speaker identification and speaker verification (SI/SV). The key benefit of this technology is that it allows VoiceXML browsers to inter-operate with third party ASR, TTS, and SI/SV servers using an open, standardized protocol. Interoperability of this nature allows a given VoiceXML solution to be comprised of components from multiple vendors, benefiting technology providers by adding value to their products, while placing greater flexibility and choice in the hands of customers.
