Abstract
In this paper, a new algorithm for encoding spectral envelope in G.729.1 for VoIP is proposed. In order to reduce allocation bits, sub-band correlation between adjacent frames is utilized. By the proposed allocation algorithm, enhanced quality of sounds can be obtained even in frame error conditions.
