Speech Signal Filters based on Soft Computing Techniques: A Comparison
  The paper presents a comparison of various soft computing techniques used for
filtering and enhancing speech signals. The three major techniques that fall
under soft computing are neural networks, fuzzy systems and genetic algorithms.
Other hybrid techniques such as neuro-fuzzy systems are also available. In
general, soft computing techniques have been experimentally observed to give
far superior performance as compared to non-soft computing techniques in terms
of robustness and accuracy.
