Cepstral MRCP Server

I would like to introduce Cepstral MRCP server as the primary UniMRCP
based solution.

I want Cepstral to be recognized as the main contributor and sponsor
of UniMRCP project.
Cepstral offers its TTS voices via MRCP using open source UniMRCP
server.

voices, Aculab's Prosody platform and UniMRCP between:

LumenVox MRCPv2 Interop

I would like to announce the successful interoperability between UniMRCP client and LumenVox ASR MRCPv2 server. This is the follow up to the successful MRCPv1 interoperability.

UniMRCP client stack can be used as a building block to provide connectivity to LumenVox MRCPv1 and/or MRCPv2 servers.
Please check out the Wiki page dedicated to the LumenVox interoperability.
http://code.google.com/p/unimrcp/wiki/LumenVoxInterop

It provides typical configurations and sample network captures. You may also add comments and share your experience there.

Thanks,
