I think that if your original grammar implementation doesn’t raise any errors and is returning output that you can evaluate, we have explored everything that is within the realm of supportable troubleshooting here, so I am going to close this as answered because I think we have explored all of the topics which have come up here at substantial length and I think there should be enough for you to examine further outside of an ongoing troubleshooting process with me.
If you have very specific questions later on (I mean, questions about a single aspect of a single implementation with a single acoustic model) it’s OK to start very focused new topics, just please create a fresh implementation you are comfortable sharing things about and you are sure doesn’t have accumulated code from different implementations, and remember to share the info in here without prompting from me so the questions don’t get closed, thanks and good luck!
