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.1 aТилков, Димитър1 aМишева, Анастасия  uhttps://naum.slav.uni-sofia.bg/en/librislavici/%D1%82%D0%B8%D0%BB%D0%BA%D0%BE%D0%B2197800648nas a2200133   4500008004100000245015500041210012700196300001400323490000600337653001700343653002900360100003300389856009200422       1977                        bul d00aКонтрастивни фонетични изследвания в Софийския университет „Климент Охридски“.0 aКонтрастивни фонетични изследвания в Софийския университет Климе  a237–2390 v210abibliography10aбиблиографии1 aТилков, Димитър  uhttps://naum.slav.uni-sofia.bg/en/librislavici/%D1%82%D0%B8%D0%BB%D0%BA%D0%BE%D0%B21977
