Към въпроса за акустичните параметри на акцентуваността в две родствени езикови системи (върху материал от българския и руския език)

The investigation proposed is part of an all-round experimental study of words with double stress in Bulgarian and Russian aimed at establishing which of the objective quantitative and qualitative characteristics of the speech sound are related to the perception of accentuation in closely related language systems with a dynamic stress. Attention is paid primarily to those acoustic parameters of vowels which are informative in distinguishing the primary from the secondary stress. The observation is restricted to the phonemes of the primary vowel triangle – a circumstance conditioning the relative character of the results obtained.
