The paper gives a phonological and acoustic description of the Luzino vowel system. The analysis showed evident phonetic changes in the last 50–60 years which are, however, not so numerous and striking as in many other Kashubian dialects. The most important of them are: heightening of stressed *[ɛ] into [ɘ̟], phonetic reduction and identification of unstressed *[ɛ] and [ə], splitting of *[ɑ̃, õ] into [VN], and disappearance of fronted allophones of /u/. The paper enabled also to describe some vowel sounds of the dialect much more precisely than it was done in the past which apply especially to *[ə] and *[ɑː]. As to the phonology, contrasts between all 9 oral phonemes established in older descriptions were retained. The original nasal vowels were, conversely, lost as phonemes and developed into sequences /Vŋ/ with various phonetic realizations of /ŋ/.
