Pronunciation recognition - speech API or algorithm

Question

Is there any API for Windows Phone - or some other method besides sending audio to a server - to recognize how correctly a particular word is pronounced?

What I'm not looking for is to recognize it semantically or against any other criteria than a source audio file for comparison (with something like a confidence level for how accurately a user says a particular word compared to the source audio file).

I've looked around quite a bit and haven't been able to find anything that could be run solely on a Windows Phone without a connection to a server.

If no API exists, is there a .NET set of classes (open source) that could be modified for use to this end?

PocketSphinx runs on Android. (See here). I am not sure if you would have a port for Windows phone. The models etc. you might use are free to be shipped. I think that with Pocketsphinx, you can also ship code.
