ENIn the paper, the nasals of the Lithuanian standard language have been analyzed: labial (/m/, /mj/), dental (/n/, /nj/) and [ŋ], the velar allophone of /n/ which occurs before [-k/-g]. Three acoustic properties of Lithuanian nasals have been analyzed: 1) first nasal formant (N1); 2) the bandwidth of the first nasal formant (B1); 3) frequency range of antiformant (Z1). Study material included 6 male and 6 female native speakers (aged 21–42). Lithuanian sonorants were analyzed in prevocalic position in CVC sequences taking into account three criteria: 1) the place of articulation; 2) palatalization (non-palatalized vs. palatalized nasal); 3) gender of speakers. The study has shown that: 1) significant differences were found between the Lithuanian velar nasals ([ŋ], [ŋʲ]) and non-velar nasals (labial [m], [mʲ] and dental [n], [nʲ]). The differences between the labial [m], [mʲ] and dental [n], [nʲ] nasals are smaller and not significant; 2) there is no single absolute distinctive acoustic feature of the Lithuanian nasals, therefore nasal sonorants must be studied comprehensively, evaluating various parameters. Keywords: Lithuanian standard language; nasals; first nasal formant; the bandwidth of the first nasal formant; antiformant. [From the publication]
