Abstract
A novel technique for speaker verification over a communication network is proposed. The technique employs cepstral coefficients (LPCCs) derived from G.729 and G.723.1 coder parameters as feature vectors. Based on the LP coefficients derived from the coder parameters, LP residuals are reconstructed, and the verification performance is improved by taking account of the additional speaker-dependent information contained in the reconstructed residuals. This is achieved by adding the LPCCs of the LP residuals to the LPCCs derived from the coder parameters. To reduce the acoustic mismatch between different handsets, a technique combining a handset selector with stochastic feature transformation is employed. Experimental results based on 150 speakers show that the proposed technique outperforms the approaches that only utilize the coder-derived LPCCs.
