Abstract:
The linear spectral pairs (LSP) are sending in CELP speech coding systems as information of linear prediction model of speech signals. These coefficients have some specific properties: the ability of sending minimal numbers of bits, monotonic values increasing etc. In this article it is proposed to use the linear spectral pairs in other sense – as a method for comparative evaluation of CELP decoded speech signals. There are defined the equations for calculating the distance between the original and decoded speech signal. With a MATLAB simulation are shown the experimental results confirming the correctness of the proposed method for comparative evaluation of CELP decoded speech signals.
