WebbThe audio dataset set is analyzed using the Mel Frequency Cepstral Coefficients (MFCC). Both the K nearest neighbor (KNN) classifier, and the artificial neural network (ANN) classifier are applied for classification purpose. The pitch is used as features which are utilized to train the ANN and the KNN for classification. http://www2.imm.dtu.dk/pubdb/edoc/imm3319.pdf Webb13 maj 2012 · speech recognition using knn.
