The paper discusses the acoustic variants of the phoneme /c/, together with the appriopriate articulatory intepretation and auditory perception assessment. The acoustic correlates and articulatory interpretation are based upon the theory of speech production introduced by G. Fant and developed by K. Stevens. The acoustic data for standard Polish provide evidence against describing the primary variant of /c/ as a postpalatal sound. The collected data clearly demonstrate that the place of articulation of /c/ sounds is further in the front part of palate, i.e. prepalatum. The same conclusion might be draw on cumulative data for dialectal varietes of Polish.
