Abstract

Evaluation of a two systems for speech enhancement is presented. A clasical Widrow dual channel noise canceller adaptive filter is used introducing the implemenation of Affine Projection Algorithm and comparing results versus traditional LMS implementation. Clasical Widrow noise canceller concept is used under reallistic input considerations, where signal of interest and noise are present at both inputs. Simple Root Mean Square Error (RMSE), Itakura-Saito Distance (ISD) and subjective evaluation tests are made in order to ease comparisons.

Keywords
