Hi, I have some files that containing some pre-determined word (with repetition). However, there might be some unknown words also in the files. I want to recognize the pre-determined word and treat the unknown words as "garbage". Does any one have idea how can I deal with the "garbage" words?

I have an example here. The pre-determine words are A, B, and C. The utterance should be:
A B C A B C A B C (the number of repitition is unknown, here I assume they are repeated 3 times)
However, sometime it will be like this:
A B C is this right A B C A B C
The "is this right" is unexpected (also unknown) words. When I do recognition, I only want to recognize A, B and C. When it reach "is this right", just use some symbol or words to substitute it.

Is this feasible? If yes, how can I do this?

Thank you.
