This paper is concerned with a spectral enhancement of Polish vowels presented in quiet and at a background of a broadband noise. The basic idea of the presented algorithm is to change a spectrum of an input signal to evoke an excitation pattern in the impaired auditory system that would be evoked by the original signal in the normal auditory system. Applying this algorithm, a spectral contrast improvement in Polish vowels was achieved, especially for first three formants. The enhancement, however, strictly depends on the vowel and the procedure changes relative levels of the vowels' formants. The spectral enhancement was achieved both for vowels presented in quiet and at a background of a broadband noise.
