Objective of this research - deriving of digital algorithm of interrelation of factors linear prediction coefficients with line spectrum vapors at speech signal call handling. This purpose is attained by the analysis of phase-frequency characteristic of the predictor filter. As a result for the first time the system of the linear algebraic equations showing explicit interrelation of factors linear prediction coefficients with line spectrum vapors and easily programmed on a computer is gained. Outcomes of theoretical calculation prove to be true experimentally. Estimations of factors linear prediction coefficients with line spectrum vapors couples are computed with a split-hair accuracy.
