The results from both tests proved to be almost the same. German and Bulgarian listeners gave very similar answers regarding the boundary „diphthong-monophthong“ and the correlation coefficients between the listeners’ answers and the physical parameters of the test stimuli were also of the same order in both cases. The answers of the Bulgarian listeners as regards the phonetic quality of the first components of the diphthongs varied in a higher degree as compared with the answers of the German listeners who identified them more „correctly“. This fact may be explained by the different phonological status of the two kinds of units.1 aГригорова, Евелина  uhttp://scripta-bulgarica.eu/en/node/2862
