ABSTRACT:
A method, a system, and an apparatus biasing a speech recognizer based on prompt context. The present invention is capable of analyzing the words used in the prompt given to the user. Then, a set of words the user is likely to say in response to the prompt is determined. The word set may be determined using a technology used by the speech recognition system, such as n-grams, grammars, or both. The speech recognition system boosts the probabilities of the analyzed words in the word set by a preconfigured amount. The preconfigured amount is selected based on collected data.
