METHOD OF AND APPARATUS FOR ENHANCING DIALOG UTILIZING FORMANT REGION

摘要

PROBLEM TO BE SOLVED: To provide a method and apparatus for enhancing dialog using formant regions.;SOLUTION: A dialog-enhancing method and apparatus boost formants of dialog zones, without changing sound zones. Then line spectrum pair coefficients based on linear prediction coding (LPC) is calculated from an input signal, whether voice zones exist in the input signal is determined, on the basis of the calculated LSP coefficients, and formant regions are extracted from the linear spectrum pair coefficients, according to whether the voice zones exist and boosted.;COPYRIGHT: (C)2005,JPO&NCIPI
