详细说明: Open G.729 Initiative Technical Documentation VoiceAge G.729 is an 8 Kbps coder that encodes/decodes speech signals using the Conjugate-Structure Algebraic-Code-Excited-Linear-Prediction (CS-ACELP) algorithm. VoiceAge G.729 is a reduced complexity version of G.729 and is bit stream interoperable with the full version. The coder operates on speech frames of 10 ms, corresponding to 80 samples at a sampling rate of 8000 samples/sec. In addition to the 10 ms speech frame duration, there is also a look-ahead delay of 5 ms, resulting in a total initial algorithmic delay of 15ms.
