The paper deals with the problem of estimation an optimal i-vector based speaker voice model using several sessions of his or her voice recordings, each of which has different signal parameters: speech duration and SNR. Our aim is to minimize inter-session variability so as to achieve minimal EER in the task of speaker recognition. We examine the influence of the main signal parameters on intersession variability and propose a model for multi-session i-vector estimation based on minimizing inter-session variability.
