Consideraciones sobre la marca acústica del acento fonológico

Resum

This paper is based on the results of the computerized acoustical analysis of a corpus composed by 57 models of utterance in 7 languages (French, Spamsh, Catalonian, Portuguese, Italian, Englísh, Russian), pronounced by several native speakers, that means 224 real utterances with 2572 syIlables (out of which 847 are stressed). Duration, intensity and fundamental frequency have been measured for every vowel, that means a global amount of 7716 absolute data in ms, db & hz (Pamies, 1994-b). Two of the aims of this investigation are presented here: 1) to compare our empirical data about the role of those parameters in the production of phonological stress with the current theories on that topic; 2) a set of criteria to verify the possibility of an interaction between the three suprasegrnentals is evaluated, including some coefficients which can vary depending on the language and on the stress position in the utterance.
