Abstract (en)

[origin: FR2884989A1] The method involves determining linear predictive coding (LPC) coefficients of one format from an interpolation over values representative of LPC coefficients of another format, between a given block (n) and a block (n-1), preceding the former block. The interpolation is dynamically performed by selecting for each current block, an interpolation factor among a preselection of factors, according to a predetermined criteria such as stationarity criteria. Independent claims are also included for the following: (1) a transcoding module; (2) a voice signal coding system; and (3) a computer program product for coding a voice signal.
