Can someone suggest a solution to this : Using Julius if I define say 3 choices in vocabulary file : choice1, choice2, choice3 and if user says something completely different say "hello" then I want julius to give me either no answer or some default answer, but its giving one of 3 choices. Any quick way to achieve this or is it necessary to understand its underlying HMM to solve this?

Thanks, Sohel
