Apparatus and method for speech recognition

Ralf Kern; Karl-Heinz Pflaum

An apparatus and a method for speech recognition are provided, by which, whereby the speech is optionally input via a microphone (14) close to the speaker or a microphone (20) remote from the speaker. A correction unit (15) is connected into the transmission channel (12) with microphone (14) close to the speaker, the correction unit modifying the electrical speech signal in such a way that it contains room transmission characteristics.
