Description

ABSTRACT:
The invention concerns a speech recognition enhancer (51) and a speech recognition system comprising such speech recognition enhancer (51), an audio input unit (41) and a speech recognizer (61, 3). The speech recognition enhancer (51) is arranged between the audio input unit (41) and the speech recognizer (61, 3). The speech recognition enhancer (51) has a parametrizable pre-filtering unit (511), a parametrizable dynamic voice level control unit (512), a parametrizable noise reduction unit (513) and a parametrizable voice level control unit (514). The parameters of these parametrizable units (511, 512, 513, 514) are adjusted to the characteristics of the specific audio input unit (41) and/or the characteristics of the specific speech recognizer (61, 3) for adapting the audio input unit (41) to the speech recognizer (61, 3).
