Basic principles of various adaptive algorithms for speech detection in a noise and their behaviour under real car noise conditions are described. Energy, spectral, cepstral, and coherence detectors are compared. All these algorithms are suitable for real time implementation with one or two microphones. High probability of correct speech/pause detection can be obtained even if signal to noise ratio is low and noises are highly nonstationary.
