Claim 14:
15. A method for adjusting a no voice activity detection (NVAD) cut-off period of an interface device that detects a plurality of spoken words and voice activities, the method comprising:
detecting periods of voice activity and periods of no voice activity within the plurality of spoken words;
parsing the plurality of spoken words according to a first grammar and a second grammar to determine if the plurality of spoken words is a complete parse according to the first grammar and a prefix to another complete parse according to the second grammar;
accessing the NVAD cut-off period calculated from a prior voice activity; and
generating a new NVAD cut-off period, which prevents cut-off of slow voice activity and improves response time to fast voice activity, by scaling the NVAD cut-off period based at least in part on determining if the plurality of spoken words is a complete parse according to the first grammar and a prefix to another complete parse according to the second grammar.
