Abstract  Abstract

A method of generating a high band excitation signal (S120), comprising dichoproceding: harmonically widening the spectrum of a signal that is based on a low band excitation signal (S80); calculating a time domain envelope of a signal that It is based on the low band excitation signal (S80), modulating a noise signal according to the time domain envelope; and combine (A) a harmonically widened signal (S160) based on a result of said harmonic widening and (B) a modulated signal (S170) of noise based on a dichamodulation result, said combination including the calculation of a weighted sum of the signal (S160) harmonically widened and the modulated signal (S170) of noise, including said calculation of a weighted sum the signal weighting (S160) harmonically widened according to a first weighting factor and the weighting of the modulated signal (S170) of noise according a second weighting factor, said method comprising the calculation of at least one between the first and second weighting factors according to at least one between (A) a periodicity measurement of a speech signal and (B) a vocal degree of a voice signal, in which the high band excitation signal is based on the weighted sum.
