Optimized Audio Classification and Segmentation Algorithm by Using Ensemble Methods

Figure 6

Mel-frequency cepstral plot (calculated for multiple frames of speech, music, and environment sound; from the plot the cepstral behavior for three different audio types can be observed; from 0 to 700 s is speech, from 701 to 1400 is environment sound, and from 1401 to 2100 s is music).
