Patent ID: 7505901

Claim:
A process for regulating a speech recognition system, in which reception characteristics of each microphone in a microphone array are controlled by an optimization unit ( 10 ), wherein speech signals are received and processed via the microphone array, and in which in the course of the processing of the speech signals, the reception characteristics of each microphone in the microphone array ( 12 ) are so controlled by the optimization unit ( 10 ), that the recognition power of a speech recognizer ( 11 ) downstream of the optimization unit ( 10 ) is optimized, wherein the speech signals received by the speech recognizer ( 11 ) are supplied by multiple parallel or quasi-parallel speech channels ( 14 ), wherein the speech recognizer ( 11 ) processes these speech channels parallel, at least in time, and compares the quality of the recognition results, produced by the speech recognizer, with each other, and wherein on the basis of this comparison: on the one hand, the speech signals from the speech channels ( 14 ) which have the potential for a best possible recognition are selected and further processed, and on the other hand, the optimization unit ( 10 ) obtains from the speech recognizer the necessary regulating signals ( 18 ), in order to optimize the reception characteristics of the microphone array ( 12 ) in regard to the respective speech channels ( 14 ) via which the respective speech signal is received which has the potential for the best possible recognition.
