In this paper, we propose an efficient vector quantization scheme of line spectral pair parameters which combines conditional split VQ with a multiple search. At first, we show the efficiency of mutiple search for two VQ schemes of LSP, split VQ and conditional split VQ. In spite of improved performance, the unavoidable increase in computational complexity makes the SVQ with multiple search unattractive. However, the reduced complexity of conditional split VQ make the combination with a multiple search realizable and very attractive. Experimental results are presented to show the efficiency of the proposed scheme, the multiple search conditional split VQ (MS-CONSVQ).
