Abstract
The exceptional capability of humans to perceive speech in varying acoustic environments could not yet be achieved by technological speech processing systems. Here, we present a novel, nonlinear acoustic sensor system including adaptation. Thereby, (short-term) adaptation is implemented using automatic gain control by discrete analog circuits. Thus, the sensor includes pre-processing capabilities like frequency decomposition, nonlinear amplification of signals and adaptation of sensing properties to varying acoustic inputs.
