	abstract = {The contrastive study of related or unrelated languages requires the separate consideration of every language level. 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 {\textendash} stress and intonation of language.},
