Abstract:In this paper, we investigate the utilization of the Normalized Pitch Frequency (NPF) as an extracted feature from speech signals to be combined with the Mel Frequency Cepstral Coefficients (MFCCs) and polynomial coefficients. The objective is to compose more robust feature vectors to various forms of degradation such as Additive White Gaussian Noise (AWGN) and music interference. A matching process is performed to determine the identity of the unknown speaker, using a trained Artificial Neural Network (ANN) a… Show more
