Abstract
An apparatus is shown for detecting speech in an audio signal obtained from an input device, the audio including speech and noise. The apparatus includes a processing circuit which includes a filter configured to smooth the audio signal. The processing circuit is configured to control the bandwidth of the filter based on characteristics of the audio signal and to provide a smoothed signal obtained from the filter to a voice activity detector configured to determine whether the smoothed signal represents speech.
