    (Color online) (a) Experimental scenario and (b)–(f) Euclidean distances of different dimensional characteristic matrices of four different samples at different SNRs. From top to bottom is car, human voice, airplane and train, respectively. The red dash is the threshold value $D_{\rm~th}$ of the Euclidean distance. The blue bar represents the characteristics matrices Euclidean distance between sample sound and corresponding template sound, while the distances between sample sound and the other template sounds are shown in green.
