1. A speech recognition data processing device comprising: a storage device; a recognition result hypothesis generation processor that generates, with reference to the storage device, recognition result hypotheses based on a result of speech recognition of an input speech signal; and an adaptation processor that rescores, with reference to the storage device, the recognition result hypotheses in a first manner according to a first output destination and simultaneously rescores the recognition result hypotheses in a second manner, different from the first manner, according to a second output destination; the system generating for the first output destination a first recognition result of the input speech signal obtained through the recognition result hypotheses rescored in the first manner and simultaneously generating for the second output destination a second recognition result of the input speech signal obtained through the recognition result hypotheses rescored in the second manner, and outputting to the respective output destinations the first and second recognition results.
