In this paper a method for speech quality estimation was evaluated simulating transmission of AMR-NB encoded speech over noisy GSM channel. The proposed system uses comparison of Time Encoded Signal (TES) processing of speech sequences, where one original and one degraded speech signal were transmitted trough GSM simulation system with AWGN noise channel. Several tests have been made on reference speech sample of single speaker with simulated bit-error loss effects on the perceived speech. The achieved results and the similarity measure scores between two TES speech sequences for various levels of noise channel conditions were compared with measured PESQ MOS values of the used channel and the correlation between them was observed.
