Abstract In this paper, the definition and properties of Line Spectral Frequency(LSF) parameters are introduced briefly. An efficient solution method of obtaining LSF parameters is presented. A new Split Vector Quantizer(SVQ) of LSF parameters is designed in LPC speech coding. The objective and subjective evaluations show that the proposed scheme offers transparent quantization quality with 25 bit/frame.

Key words： Speech coding Linear prediction Vector quantization Line Spectral Frequencies
