A restricted temporal decomposition method is presented for line spectral frequency (LSF) parameters. The proposed method interpolates an LSF vector trajectory efficiently while conserving the LSF ordering property. Experimental results show that interpolated LSF parameters can be transparently quantised at a rate of 753 bit/s
