Claim One:
1. A computer-implemented method comprising: obtaining a candidate transcription that an automated speech recognizer generates for an utterance; determining a particular context associated with the utterance; obtaining a context profile associated with the particular context, wherein the context profile specifies (i) one or more n-grams, and, (ii) for each of the one more n-grams, a value that reflects an extent to which the candidate transcription includes the n-gram specified in the context profile; determining that a particular n-gram that is included in the candidate transcription is included among a set of undesirable n-grams that is associated with the context; adjusting a speech recognition confidence score associated with the transcription based on determining that the particular n-gram that is included in the candidate transcription is included among the set of undesirable n-grams that is associated with the context, wherein adjusting the speech recognition confidence score associated with the transcription comprises multiplying a value representing the speech recognition confidence score and the value that reflects an extent to which the candidate transcription includes the n-gram specified in the context profile; and determining whether to provide the candidate transcription for output based at least on the adjusted speech recognition confidence score.
