Abstract

Line spectrum pair (LSP) was first introduced by Itakura (1975) as an alternative representation for the LPC spectral information. It was later found that LSPs have very desirable quantization and interpolation properties. Interpolation of LSPs at the frame boundaries results in a synthesized speech that is smoother and has higher quality. This paper… (More)
