Apparatus and method for improving speech intelligibility in background noise by amplification and compression

An apparatus for generating a modified speech signal from a speech input signal, wherein the speech input signal comprises a plurality of speech subband signals, wherein the modified speech signal comprises a plurality of modified subband signals, wherein the apparatus comprises:

• a weighting information generator for generating weighting information for each speech subband signal of the plurality of speech subband signals depending on a signal power of said speech subband signal, and
• a signal modifier for modifying each speech subband signal of the plurality of speech subband signals by applying the weighting information of said speech subband signal on said speech subband signal to acquire a modified subband signal of the plurality of modified subband signals,
• wherein the weighting information generator is configured to generate the weighting information for each of the plurality of speech subband signals and wherein the signal modifier is configured to modify each of the speech subband signals so that a first speech subband signal of the plurality of speech subband signals comprising a first signal power is amplified with a first degree, and so that a second speech subband signal of the plurality of speech subband signals comprising a second signal power is amplified with a second degree, wherein the first signal power is greater than the second signal power, and wherein the first degree is lower than the second degree.
