A device for reproducing information or executing functions in which first data, which represent information to be reproduced or functions to be executed, and second data, which assist the voice recognition, are realized on the same physical storage medium, which can be easily exchanged by a user. The device serves especially for bidirectional acoustic communication for entertainment and/or education purposes. Multimedia smart cards are especially intended as the storage medium.

Device for reproducing information or executing functions

Speech recognition with a speaker-independent speech recognition method is possible for voice signals newly added by a user using the computer unit. Imaging of the voice signal onto stored phoneme feature vectors is implemented for each voice signal to be newly incorporated. A number of possibilities of imaging are compared to one another and the best phoneme representation of the imaging is employed as phoneme presentation for the new word. The voice signal is then stored in a user memory with the phoneme presentation.

Computer unit for speech recognition and method for computer-supported

A digital signal processor employable for utilization for speech processing or for some other pattern recognition overcomes the weaknesses of digital signal processors given the subtraction with following amount formation that must often be implemented in these applications, an auxiliary hardware is provided that contains the feature vector that is to be compared to reference feature vectors from the dictionary in a separate memory. The calculating work is thereby implemented by a separate arithmetic unit that provides a separate difference-forming and amount-forming unit for each feature comparison. The number of clock cycles of the digital signal processor required per comparison can be dramatically reduced by the invention. A suitable addressing method thereby assures that it is always corresponding features of the individual feature vectors that can be compared to one another.
