Abstract
The technology described in this document can be embodied in a computer-implemented method that includes obtaining a plurality of portions of a speech signal, and obtaining a plurality of frequency representations by computing a frequency representation of each portion of the speech signal. The method also includes generating, by one or more processing devices, a time-varying data set using the plurality of frequency representations by computing an entropy of each frequency representation of the plurality of frequency representations, and determining, by the one or more processing devices, boundaries of a speech segment using the time-varying data set. The method further includes classifying the speech segment into a first class of a plurality of classes, and processing the speech signal using the first class of the speech segment.
