Maybe Arsen can chime in. He is the author of unimrcp and the previous openmrcp.

I would assume it would be a few k to hire some developers to work on the module.
The new library is working so it should be straightforward. I am willing to help answer questions
for whomever wants to code it and we will even try to get the module started but we need to add
it to a very large todo list.

Apparently you did. I was responding to comments/claims of another poster by relating my experiences and wishing that PS in FS would preform better.

I'm missing something, What is your point exactly?

I *just* explained that we want to support unimrcp so you can use Prophecy if you wish so we get it, there is no need to continue to complain. I tried to tell you that we are short on time and we are trying our best.

We had openmrcp and the devloper discontinued the project. Now we need to get rid of it and switch to unimrcp.

If you recall, you called us for consulting, then spent an hour on the phone gathering free information then proceeded to get all kinds of free help on this list using the free software we have made available to you. It's great that Prophecy is the only place you want to spend any money and I encourage you to do so we can connect you with Voxeo any time. But what else exactly do you want from us?

You may want to factor in that your limited experience and particular requirements contribute to your trouble setting everything up so clearly the pocketsphinx route is not for you. (You are only the 2nd person to try it on windows for instance)

I keep reading all of your emails and I am trying to understand exactly what you want from us.

Hi Paul,

If you mean fixing up pocketsphinx (ps) for telephony instead of or in addition to working on unimrcp then this is the site of the person who created ps and he may have some advice.

http://www.cs.cmu.edu/~dhuggins/

Also, this was a post from the sphinx forums for adapting pocketsphinx for telephony.

http://sourceforge.net/forum/message.php?msg_id=5621913

I don't know how accurate it is but if accurate then here is that post to give you some of the issues involved:

-----------------
Well, there are issues in both the decoder and the interface with the
telephony application.

First about the decoder, pocketsphinx right now is the most supported
and most feature-reach decoder of the family, but in general it's still
oriented on the embedded devices. For telephony applications you
probably need to extend it a lot. The features that are currently
missing are probably:

* Out-of-box support for multiple recognizers (probably more a freeswitch
issue and a model training issue, for example we have no free
male/female model).

* Speaker clustering.

* Automatic VTLN estimation from pitch (This looks simple).

* Good endpointer.

* Discriminative training support in SphinxTrain (Huge task).

* Good and clean support for a garbage model to be able to filter out
out of grammar words.

* Embedded RASTA extraction and RASTA model training.

* Advanced features extraction

Another issue is dialog tracking and understanding. CMU folks are doing
work on dialog systems, for example Raven is available

http://www.ravenclaw-olympus.org/systems_overview.html

It would be worth to look on it and try to integrate it into
freepbx. Decoder will need to support combined language model. As well
as you'll need a component for postprocessing. The postprocessing includes
disfluency removal, text normalization, text boundary detection. Integration
with nltk probably useful for sense extraction.

If you need more details on any of the above, feel free to ask.

Well I also want to have someone take pocketsphinx and flite and build an opensource speech server and maybe gain some momentum to improve it. btw pocketsphinx supports jsgf, I need to update mod_pocketsphinx to do that but I want to work with DHD to figure out how to load the dictionary once... and just load grammar files moving forward.

We already have been collaborating with the maintainer of pocketsphinx for more than a year now, that's why we have a mod_pocketsphinx. His latest releases are based on our feedback so we are already doing that.
