1. A method for increasing the accuracy of a voice recognition system, comprising: initiating a voice processing session for a first user, wherein the voice processing session is configured to match a voice pattern derived from one or more words spoken by the first user with entries in a word-usage probability table, based on the probability of the one or more words being spoken by the first user; during the voice processing session initiated for the first user, monitoring for an occurrence of a word-usage anomaly, wherein the word-usage anomaly occurs when an observed usage frequency for a given one or more words differs, by a predetermined magnitude, from an expected frequency recorded in the word-usage probability table for the given one or more words; in response to the occurrence of the word usage anomaly, increasing the expected frequency for the given one or more words in the word-usage probability table; and transmitting an indication of the observed anomaly to a voice processing session initiated for a second user.
