An architecture providing a human interface includes a user input device, a studio or workplace receiving an output of the user input device, the studio being capable of storing and sharing information, and a plurality of agents or functional modules connected to supply/receive data from the studio. The agents are connected in parallel and perform processing as distributed and cooperative processing of functions by the user. The agents are independent components having independent functions performing processing on data in the studio to receive and store items of information, respectively, from and to the studio as a shared information medium, the studio being accessible to the user and to the plurality of agents. Each of the plurality of agents can be independently started depending upon a status of the studio.

This speech recognition system uses a converted-spectrum for comparison of unknown and prestored reference signals. The comparison distance is modified by a weighting factor W to emphasize differences. A straight line approximation of the short term spectrum provides a datum against which the original spectrum is differenced to provide the converted spectrum, and provide deviation signs which are used to modify an initial prestored weighting factor P to form W.
