The analysis aims at establishing the objective change of that quantity which is registered through its absolute values in the so-called long and short vowels. The object of analysis is a contrastive study of the data obtained from one and the same phonological material, pronounced by English and Bulgarian informants; the ultimate aim is to check M. Durand’s statement about the linguistic significance of the basic tone in the differentiation between the English long and short vowels.1 aДеспотова, Вера, Г.  uhttp://scripta-bulgarica.eu/bg/biblio/despotova1981
