Abstract

The implementation and evaluation of our new acoustic echo canceller for a videotelephony-enabled business phone is presented. The developed echo canceller has the following features, the sufficient echo and noise suppression, low processing delay, natural-sounding processed speech and low computational cost. The experimental results demonstrate that the new echo canceller suppresses the echo and noise sufficiently and thus achieves natural-sounding speech.
