Optimized Audio Classification and Segmentation Algorithm by Using Ensemble Methods

Figure 5

Spectrum flux plot (calculated for multiple frames of speech, environment sound, and music waveforms; from the plot it can be easily observed that spectrum flux of speech which is from 0 to 280 s is greater than music spectrum flux which is from 561 to 850 s. And the spectrum flux for environment sound which is 281 to 560 s is highest).
