- W2065164808 abstract "an improved method is proposed to skip the look- ahead period in this paper. The improved method uses the autocorrelation algorithm to calculate the Linear Prediction (LP) coefficients and then the LP coefficients are employed to extrapolate new samples for replacing the look-ahead samples. To evaluate the quality of this method, perceptual evaluation of speech quality (PESQ) and the A/B listening test method are designed for the objective evaluation and subjective evaluation. The reconstructed quality of the modified method is near to the original AMR codec, at the same time, the delay of the improved method is lower 5ms than the original method." @default.
