Description

ABSTRACT:
A speech-recognition system includes a speech-recognition arrangement (1) and a learning device (5) for adapting the speech-recognition arrangement to the characteristic pronunciation of a given speaker during an adaptive learning mode. Certain words are applied during a learning procedure to the speech-recognition arrangement via a keyboard and, in addition, the sound signals associated with these certain words and originating from the given speaker are fed-in via a microphone. The sound signals corresponding to a spoken text are fed into the speech-recognition arrangement via a storage medium which can be scanned by a reproducing device. The reproducing device may be implemented in the form of a recording and reproducing device (7). The sound signals which are fed in to the system during a learning procedure of the speech-recognition arrangement are first recorded onto the storage medium and immediately thereafter are scanned from the storage medium and are fed into the speech-recognition arrangement.
