In this paper we revise the claim made by Halle & Stevens (1995) and Maddieson & Ladefoged (1996) that the Polish alveolo-palatal fricatives [ɕ, ʑ] are palatalized post-alveolars [ʃj, ʒj]. On the basis of perceptual experiments we show that alveolo-palatal fricatives and palatalized post-alveolars are two separate sounds which are distinguished not only by Polish native speakers but also by German ones. This claim is partly attested by centre of gravity measurements of the two sibilants.
