摘要： According to the invention, in order to enlarge the band width of a narrow-band filtered voice signal in a simple and cost-effective manner, without reducing the quality, the narrow-band filtered voice signal is estimated in terms of frequency components which are higher than a first frequency limit and lower than a second frequency limit, in a separate manner (i.e. according to different independent methods), and is enlarged on the basis of said estimation. The estimation can preferably be carried out either in the temporal region or in the frequency region.
