Abstract :
A spectral sharpening process suitable for speech enhancement and noise reduction is presented. The speech enhancement feature is an efficient precompensation technique for the reduced frequency selectivity encountered among many hearing impaired people. The noise reduction scheme has wider applications. A particular characteristic of the approach is its virtually delayless performance and its structure which easily lends itself to integration
