Automatic speaker recognition for mobile communications using AMR-WB speech coding

摘要

The aim of this paper is to investigate the influence of Adaptative Multi-Rate Wideband (AMR-WB) speech coding on Distributed Speaker Recognition (DSR). The main goal is to improve speaker recognition performance without resynthesizing the speech waveform in mobile communications. For this purpose, we have implemented a method in order to extract the acoustic features in the compressed domain, directly from encoded bitstream. The obtained results, using ARADIGIT database, show that the proposed approach, with GMM and SVM models, using ISF (Immittance Spectral Frequency) parameters through a noised channel (AWGN and Rayleigh) are promising.
