Parallel elements may be present on certain language levels and be lacking on others. The problems considered in the present paper are related to the inherent acoustic characteristics of vowels: the fundamental frequency, the intensity and duration which, on the one hand, have a universal nature because of the articulatory apparatus common to all people; on the other hand, they reflect the specific features conditioned by the system of a particular language. The inherent acoustic characteristics of the Bulgarian vowels are compared to those of corresponding vowels of other languages with a view to establish the common tendencies and deviations in every language. The study of the inherent characteristics of vowels is a basic and indispensable stage in the experimental investigations of the suprasegmental units – stress and intonation of language. %B Съпоставително езикознание / Сопоставительное языкознание / Contrastive linguistics %V 3 %P 3–10 %G bul %N 2
