Architecture of the perceptual feature extraction and the classification system. The reference set is shared by both the training and the test datasets. For each training/test audio utterance, N perceptual vectors are extracted and fed into a classifier. Classifier design has been performed based on the perceptual features extracted from the training data. Similarly, the test features are derived from the test data. S-MV has been used for the category labeling.
