Claim 0:
1. A processor-implemented method for voice command recognition, comprising:
generating an augmented grammar candidate set based on a pronunciation dictionary and an original grammar set, wherein the original grammar set comprises voice commands to be recognized and each element of the augmented grammar candidate set, comprises a variation of one of the voice commands from the original grammar set, wherein the variation is based on a probability decoding of the one of the voice commands in the pronunciation dictionary;
generating an augmented grammar set by adding one or more elements of the augmented grammar candidate set into the original grammar set;
determining a command recognition accuracy, a false-alarm rate, and a mis-detection rate for a given augmented grammar candidate set; and
determining the false-alarm rate comprises determining the false-alarm rate for each element of the augmented grammar candidate set based on an out-of-domain data set comprising a set of utterances that do not correspond to any one of the voice commands to be recognized.
