• The present paper offers a summary of the results of two earlier experiments (Nawrocki and Gonet 2004; Nawrocki 2004), in which acoustic properties of the voiceless velar fricative phoneme /x/ in Southern Polish were investigated. As is found in both studies (Nawrocki and Gonet 2004; Nawrocki 2004), speakers of both genders favour glottal articulation, with partial or full voicing. Word final contexts are decisively in favour of [x]. The word initial, prevocalic positions seem to allow quite a number of allophonic variants of /x/ . These are: [x], [ɦ], [ç] and, additionally, the voiceless glottal, the pharyngeal or the epiglottal [h]/[ħ]/[ʜ]. Another factor taken into account is the coarticulation effect of the vocalic context on the choice of articulation. Based on the results of the experiments, a reformulated allophonic composition is proposed for Polish /x/. It makes room for previously unconsidered pharyngeal and glottal allophones. In order to inspect the acoustic properties of the allophones of Polish /x/ further, their static and dynamic spectral features are compared to those of phonetically similar sounds in other languages where they have the status of independent phonemes. Special attention is paid to the distribution of spectral peaks and their intensity. The fact that in Polish there are no 'back' fricative phonemes that would contrast with /x/ creates a wide range of acceptable allophonic articulations that cannot be challenged from either articulatory or perceptual points of view.
