Abstract  Abstract

FIELD: physics; acoustics. ^ SUBSTANCE: invention relates to processing broadband voice signals. According to one embodiment the broadband voice encoder includes a narrow-band encoder and a high frequency band encoder. The narrow-band encoder encodes the narrow-band part of the broadband voice signal as a set of filter parametres and the corresponding encoded driving signal. The high frequency band encoder encodes part of the high frequency band of the broadband voice signal in accordance with the high frequency band signal to obtain a set of filter parametres. The high frequency band encoder generates a high frequency band signal by applying a nonlinear function to the signal based on the encoded narrow-band driving signal to generate a spectrally spread signal. ^ EFFECT: broadening of a narrow-band voice signal to support transmission and/or retention of broadband voice signals when transmission capacity increases. ^ 40 cl 45 dwg
