In this paper an approach based on the use of different frame lengths for the feature extraction process in the training and recognition phases of a speaker verification system is presented. It is able to sensibly reduce the ER and the degradation on performance related to the training/verification feature mismatch. The potentiality of the approach are investigated in an a-posteriori search of the best combination to be adopted. A prototype of an expert system is also presented in order to automatically search, in real time operating conditions, the optimal combination of parameters. Tests have been performed on a set of speakers whose speech productions were spanned over approximately 3 months.
