Abstract: Systems and techniques for analyzing voice recognition results in order to improve efficiency and accuracy of voice recognition. When a voice activated module undertakes a voice recognition attempt, it invokes a voice recognition module that constructs a list of voice recognition results. The list is analyzed by a results postprocessor that employs information relating to past recognition results and user information to make changes to the list. The results postprocessor may delete results that have been previously rejected during a current recognition transaction and may further alter and reorder the results list based on historical results. The results postprocessor may further alter and reorder the results list based on information relating to the user engaging in the recognition attempt.

Abstract: Systems and techniques for improved user prompting. A system according to one aspect of the invention includes a central server hosting various modules providing services to users. The modules suitably employ voice recognition in order to interpret user inputs. Each module has access to user information that includes information indicating the user's experience with each function of each module. When a module needs to issue a prompt to the user, it retrieves and examines the user information to determine the user's experience with the module and function. Suitably, each module is operative to categorize a user as belonging to an experience category, such as novice, intermediate and expert based on the user's level of experience with the function. The module selects a prompt associated with the user's level of experience with the function and presents it to the user.

Abstract: Systems and techniques for improved efficiency and accuracy in voice dialing and directory lookup applications. A voice dialing module receives an input from a user and examines a directory to identify recognition results matching the voice input. A list of recognition results matching the voice input is constructed, the entries being ranked by confidence. A called party cache for each user includes entries for parties the user is likely to call. Once the result list has been constructed, the voice dialing module compares the list with the called party cache in order to determine if entries in the list appear in the cache. If an entry in the result list appears in the cache, the result list is reordered in order to take into account the increased likelihood that an entry appearing in the called party cache will be an entry the user wishes to call.
