11 Denoising Human 	 Speech Signals Using Chaoslike Features, Phys Rev Lett.
 









Abstract: A local projective noise reduction scheme,
originally developed for low-dimensional stationary
deterministic chaotic signals, is successfully applied to human
speech. This is possible by exploiting properties of the speech
signal which resemble structure exhibited by deterministic
dynamical systems. In high-dimensional embedding spaces, the
strong inherent nonstationarity is resolved as a sequence of
many different dynamical regimes of moderate
complexity.
