Ruslan Shevchuk · 2007
In this paper, an efficient method of converting speech codec formats between G.723.1 and G.729A is proposed. The method is composed of four steps: LSP conversion, pitch conversion, adaptive codebook search and fixed codebook search. Subjective results show that the proposed method has shorter delay than classical tandem method.
