I would like to announce the availability of PocketSphinx ASR plugin for UniMRCP server.

PocketSphinx UniMRCP server can be used with an MRCP compliant client, which supports JSGF grammar.
Currently supported ASR features are as follows:

Methods:

• DEFINE-GRAMMAR
  
• RECOGNIZE
  
• GET-RESULT
  
• START-INPUT-TIMERS
  
• STOP

Events:

• START-OF-INPUT
  
• RECOGNITION-COMPLETE

Headers:

• Noinput-Timeout
  
• Recognition-Timeout
  
• Completion-Cause
  
• Completion-Reason
  
• Save-Waveform

Grammar: JSGF

For the instructions on how to build and configure PocketSphinx with UniMRCP refer to
http://code.google.com/p/unimrcp/wiki/PocketSphinxPlugin

Please note, everything is working now, nevertheless this is basic availability only.
I have mostly tested the integrated solution in the following setup
SipPhone -> FreeSWITCH/UniMRCPClient -> UniMRCPServer/PocketSphinx

However it requires further testing in different environments from different speakers, e.t.c.
In other words, your feedback is welcome.

Thanks,

I would like to present the ecosystem of the project I thought about
recently.
I used to focus primary on the software development, which is
definitely crucial task towards successful project, but still is not
enough. I want to establish an ecosystem which will "work" for all of
us.
The key components are:

1. Community
The role of community in an open source project development is
evidence. I have been trying to build robust community around the
project. The community is not so big and active at the moment, but at
least it keeps growing. I really welcome and appreciate everybody's
input.

2. Sponsorship
Sponsorship ensures the health, sustainability and encourages growth
of the project
www.unimrcp.org/sponsorship

3. Partnership
I'm looking forward for technology related partnership in order to
deliver complete, seamlessly integrated and carefully tested
solutions.
www.unimrcp.org/partnership

4. Services
Commercial support packages insure the successful deployment of the
projects you develop.
Custom development options are also available.
www.unimrcp.org/services

This is just the way I see the project can be further evolved.
Actually nothing is going to be changed dramatically. Meantime please
feel free to discuss any suggestions and thoughts you may have.

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.

Learn more about the solution:

Also read the press release about successful interop of Cepstral's TTS
voices, Aculab's Prosody platform and UniMRCP between:

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,
