	abstract = {The acoustic parameters of the German [ə] vowel and its Bulgarian correspondences are discussed contrastively. Their phonological status in the two respective languages is explained in terms of spectral and functional characteristics. The results of the theoretical study have practical significance too. They can be used to assist Bulgarian learners in mastering the German [ə] vowel on the basis of its correspondences in Bulgarian.},
