Abstract (en)

[origin: DE19811879C1] The invention relates to a device and method for speech recognition. Voice signals are inputted optionally by means of a microphone (14) placed in proximity to the speaker or by means of a microphone (20) placed remotely from said speaker. A correction unit (15), connected in the transmission channel (12) with the microphone (14) placed in proximity to the speaker, modifies the electrical voice signal so that said signal has spatial transmission features.
