Abstract
A method and system prevent the entry of confusingly similar phrases (60) in a vocabulary list (10) of a speaker-dependent voice recognition system. The method first receives (20, 30, 50) and enrolls the phrase (60) for adding to vocabulary list (10). Next, probabilities (62) are assigned to all phrases (12). Probabilities (62) assigned to already existing phrases are greater than the probability (64) assigned to the phrase (62) that the user wants to add. The phrase (60) to be added is received a second time and compared to the modified vocabulary list (61) that includes first-received phrase (60). Next, the method indicates whether the second-received phrase matches a phrase (12, 14, 16) on modified vocabulary list (61) other than first-received phrase (60).
