  • Abstract
    Line spectral pair (LSP) coefficients have been proposed as alternative representations of LPC parameters for low-bit-rate speech coding. The letter presents an LMS-type adaptive digital filter for directly calculating even-order LSP coefficients on a sequential basis. The technique is demonstrated for fourth-order adaption and may be generalised to higher orders.
