Abstract
A discrete speech recognition system has a default grammar with keywords and non-keywords. Upon detecting a non-keyword, the speech recognition system performs the function associated with the detected word. Upon detecting a keyword in the default grammar, the speech recognition system temporarily expands its active grammar list from the default grammar to a ballooned grammar that includes both the words in the default grammar and the additional words triggered by detection of the keyword. In this manner, the operator still has the option to select a word from the original grammar, or choose a word from the additional second-tier list. The ballooned grammar remains active until the operator makes a new selection. The speech recognition system then returns to the default grammar.
