9. The results postprocessor of claim 8 , wherein the changes to the results list include removing results that have been rejected during a current recognition transaction.
8. A results postprocessor for improving efficiency and accuracy of voice recognition, comprising: a repository of information relating to a current voice recognition attempt; and a processing module for processing potential voice recognition results in a result list, the potential voice recognition results representing members of a collection of elements representing potential matches to a voice input under consideration in a current voice recognition attempt, each potential voice recognition result having an associated confidence level, the processing module being operative to examine information in the repository relating to the current voice recognition attempt and to make changes to a results list compiled in response to a voice input, the changes being made based on the information stored in the repository, the changes associating a higher priority with results in the results list that are indicated to have a higher priority of matching the voice input based on information in the repository relating the characteristics of elements of data collection; and wherein the processing of the list of potential voice recognition results comprises comparing the associated confidence levels of the potential voice recognition results to an upper threshold and a lower threshold, wherein the potential voice recognition results are kept if the associated confidence levels are above the upper threshold, the potential voice recognition results are not kept if the associated confidence levels are below the lower threshold, and the potential voice recognition results with associated confidence levels between the upper threshold and the lower threshold are only kept if they match any of the past results of recognition attempts.
