Feature Extraction Using LPC-Residual and MelFrequency Cepstral Coefficients in Forensic Speaker Recognition

Abstract: Abstract-In this paper, we investigated the form to improve the performance in the recognition, involved at the forensic area. To improve, we use Linear Predictive Coding (LPC) and it residual; it was compared with Mel Frequency Cepstral Coefficients (MFCC). The classification technique was Gaussian Mixture Model (GMM). The collection data is in Spanish language, using spontaneous speech from 37 male speaker of Mexican Spanish, we have three recordings, between each recording exist 3 week and one month of sepa… Show more
