Speaker verification using a new representation based on a combination of MFCC and formants
Anis Mezghani, Douglas D. O’Shaughnessy · 2006
The purpose of this study is to investigate a new representation for automatic speaker verification using MFCC, formants and a combination of MFCC/formants. Verification is carried out using a weighted Euclidean distance also known as a Mahalanobis distance. The weighting coefficients are determined depending on their utility in the verification process. We report on extensive experiments that show the pertinence of the hybrid representation and the superior performance of the scheme
