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.
2. A speech recognition data processing device comprising: a storage device; a common data processor that generates, with reference to the storage device, recognition result hypotheses for a speech supplied from one speech input unit, the recognition result hypotheses not being biased to either a first application or a second application; and an adaptation data processor that receives the recognition result hypotheses from the common data processing unit and that simultaneously generates, with reference to the storage device, a first recognition result specialized for the first application and a second recognition result, different from the first recognition result, specialized for the second application, and outputs the respective recognition results to the applications.
