5. The system according to claim 3 , wherein the storage device comprises: a speech recognition data storage unit that stores therein acoustic models and language models as the data on the processing of the speech recognition process common to the respective applications; and an adaptation data storage unit that stores therein word weight information on recognition vocabularies and parameters for rescoring the recognition result hypotheses as the data on the processing of the speech recognition process that is different according to the each application.
3. The system according to claim 2 , comprising: a storage device that stores therein speech recognition data on processing of a speech recognition process common to said first and second applications and data on adaptation processing of the speech recognition process that is mutually different in accordance with the respective applications; wherein the common data processing unit includes: a feature extraction unit that extracts a feature of a speech supplied from a speech input unit; and a recognition result hypothesis generation unit that generates the recognition result hypotheses for the feature extracted by the feature extraction unit, using the speech recognition data on the common processing stored in the storage device; and wherein the adaptation data processing unit includes: a plurality of adaptation units that simultaneously generate recognition results individually specialized for the respective applications, using the data on the adaptation processing stored in the storage device, based on one of the recognition result hypotheses and supply the recognition results to the corresponding applications, respectively; the recognition result hypothesis generation unit that generates the recognition result hypotheses being made common to the applications of the supply destinations.
