The aim of this paper is to demonstrate the appearance of spectral differences of formant structures of a chosen vowel that occurred after compressing PCM sound data using a given compression method. The experiments carried out by the author show that sound data compression does not affect the significantly stability of formant frequency distributions in terms of statistics, as long as it does not introduce random, stochastic component into the original speech signal.
