Abstract:
A speech recognition support method applied to a system to retrieve a map in response to a user's input speech, comprising the steps of:recognizing the user's input speech; obtaining a plurality of recognition candidates as the recognition result; extracting, if the first candidate in the plurality of recognition candidates represents a point on the map, the recognition candidates each representing a point on the map from the plurality of recognition candidates; calculating a score of each of the extracted recognition candidates by adding a function value of distance between a point of each recognition candidate and a base point on the map to a value of similarity degree between the each recognition candidate and the input speech; deciding whether the distance of the recognition candidate of the highest score is above a threshold; and outputting, if the distance is above the threshold, an inquiry to confirm whether the recognition candidates of predetermined number of higher score are correct to the user in order.
