A method of improving perceived loudness and sharpness of a reconstructed speech signal delimited by a predetermined bandwidth, comprising the steps of: providing a speech signal; separating said speech signal into at least a first signal portion based on a first bandwidth portion of said predetermined bandwidth, and a second signal portion based on a second bandwidth portion of said predetermined bandwidth, said first bandwidth portion corresponds to low frequency bands of said provided speech signal, and said second bandwidth portion corresponds to high frequency bands of said provided speech signal; adapting said first signal portion to emphasize at least a predetermined frequency or frequency interval within said first bandwidth portion, the method being characterised in that said step of adapting comprises the step of filtering said first signal portion according to any of the following filter functions H(z): H z = α ⋅ z − 2 + β ⋅ z − 1 − γ + β ⋅ z + 1 + α ⋅ z + 2 with coefficients α = 0.1. β = 0, γ = 0.85, or H z = α ⋅ z − 1 − β + α ⋅ z + 1 with coefficients α = 0.06 and β = 0.66, or H z = 1 − μ ⋅ z − 1 with coefficient μ = 0.2, whereby at least part of the energy of the first signal portion is distributed towards a selected frequency in said first bandwidth portion and simultaneously at least another part of the energy of said first signal portion is distributed towards a selected high frequency interval of said first bandwidth portion; reconstructing said second signal portion based on at least said first signal portion or said adapted first signal portion; combining said adapted first signal portion and said reconstructed second signal portion to provide a reconstructed speech signal with an overall improved perceived loudness and sharpness. providing a speech signal; separating said speech signal into at least a first signal portion based on a first bandwidth portion of said predetermined bandwidth, and a second signal portion based on a second bandwidth portion of said predetermined bandwidth, said first bandwidth portion corresponds to low frequency bands of said provided speech signal, and said second bandwidth portion corresponds to high frequency bands of said provided speech signal; adapting said first signal portion to emphasize at least a predetermined frequency or frequency interval within said first bandwidth portion, the method being characterised in that said step of adapting comprises the step of filtering said first signal portion according to any of the following filter functions H(z): H z = α ⋅ z − 2 + β ⋅ z − 1 − γ + β ⋅ z + 1 + α ⋅ z + 2 with coefficients α = 0.1. β = 0, γ = 0.85, or H z = α ⋅ z − 1 − β + α ⋅ z + 1 with coefficients α = 0.06 and β = 0.66, or H z = 1 − μ ⋅ z − 1 with coefficient μ = 0.2, whereby at least part of the energy of the first signal portion is distributed towards a selected frequency in said first bandwidth portion and simultaneously at least another part of the energy of said first signal portion is distributed towards a selected high frequency interval of said first bandwidth portion; reconstructing said second signal portion based on at least said first signal portion or said adapted first signal portion; combining said adapted first signal portion and said reconstructed second signal portion to provide a reconstructed speech signal with an overall improved perceived loudness and sharpness.
