Auditory Contrast Spectrum for Robust Speech Recognition

  title={Auditory Contrast Spectrum for Robust Speech Recognition},
  author={Xugang Lu and Jianwu Dang},
Traditional speech representations are based on power spectrum which is obtained by energy integration from many frequency bands. Such representations are sensitive to noise since noise energy distributed in a wide frequency band may deteriorate speech representations. Inspired by the contrast sensitive mechanism in auditory neural processing, in this paper… CONTINUE READING
