Hello Bruce

We successfully deployed it and now saving thousands on commercial ASR
ports. It seems users are rather happy with it. The recognition seems
pretty accurate. Of course it has it's own limitations but so any
other technology. It will not hurt if some of your users will benefit
from ASR.

Yes, that should work. It also supports JSGF grammars, so you should
be able to recognize digit strings easily.

And if you want something serious, there are at least two open source products
providing ASR over standard MRCP protocol. They also use CMUSphinx, so
provide the same accuracy

Cairo http://www.speechforge.org/

Though Cairo is a bit dated.
