This is a simple method for silence removal and segmentation of audio streams that contain speech. The method is based in two simple audio features (signal energy and spectral centroid). As long as the feature sequences are extracted, as thresholding approach is applied on those sequence, in order to detect the speech segments.

IMPORTANT UPDATE:
More advanced silence removal and general audio analysis methods can be found in the MATLAB AUDIO ANALYSIS LIBRARY (http://www.mathworks.com/matlabcentral/fileexchange/45831-matlab-audio-analysis-library) which is part of the book INTRODUCTION TO AUDIO ANALYSIS: A MATLAB APPROACH (http://www.amazon.com/Introduction-Audio-Analysis-MATLAB%C2%AE-Approach/dp/0080993885)
