ENIn this paper the main spectral characteristics of the following Lithuanian and Latvian sonorants and their velar allophones are briefly described: Lith. /m/, /mj /, /n/, /nj /, [ŋ], [ŋ j ] and Lat. /m/, /n/, /ɲ/, [ŋ]. Until now, there has been only one comparative study on acoustic features of Lithuanian and Latvian nasals using a similar methodology [11]. For the Lithuanian part of the study, isolated sequences (of CVC type), as well as disyllabic, mostly nonsense words (of CVCV type; in the case of [ŋ], [ŋ j ], VCCV type) were selected, while for the Latvian language isolated monosyllabic sequences (of CVC type; in the case of [ŋ], CCVCC type) were analysed. Only the first non-stressed consonant is the object of this paper. [From the publication]
