Welcome

Media Resource Control Protocol (MRCP) allows to control media processing resources on the network using a distributed, client/server architecture. The main media processing resources specified by the MRCP standard are

  • Speech Synthesizer (TTS)
  • Speech Recognizer (ASR)
  • Speech Recorder (SR)
  • Speaker Verifier (SV)

MRCP is not a standalone protocol and it relies on various VoIP protocols such as

  • SIP (MRCPv2), RTSP (MRCPv1) session management
  • SDP offer/answer model
  • RTP/RTCP media streaming

UniMRCP is an open source cross-platform MRCP project, which provides everything required for the implementation and deployment of both an MRCP client and an MRCP server. UniMRCP encapsulates SIP/MRCPv2, RTSP, SDP and RTP/RTCP stacks and provides integrators with MRCP version independent API.

Everybody is welcome to join the community, use and make the project better by participating in discussions, raising issues, providing patches.
