Ahots murmurikatuaren zenbait ezaugarri akustikoz

Abstract

The main objective of this research is to analyze the acoustic characteristics of whispered voice. To this end, the sample consists of 36 phrases, of which 18 are produced in modal voice and the other 18 in a whispered voice. We used 12 questions to observe the accent placement and 6 to examine the intonational proprieties and, along with the analysis of vowel formants for [a]. The informant who answered the survey was a 23-year old woman from Igorre. Sentences were produced in her mother tongue, namely, the local variety of Igorre. Results can be summarized as follows: (1) whispered voice shows no f0 along with lower rates of intensity. The most notable characteristics of the murmured voice, compared to the common voice, are the absence of f0 and a lower intonation; (2) with respect to duration, whispered voiced were longer than modal voice; (3) The mean average for vowel formants F1 and F2 were higher for whispered voice, suggesting that [a] is produced more opened and fronted than in modal voice. (4) the main acoustic correlate is duration for whispered voice; (5) the stressed syllable is always longer than the unstressed syllable; finally, (6) in the expressive phrases and in the distinction of the yes / no questions, duration and intensity are used as acoustic correlates of pitch, but in the last syllable of the phrase there is greater contrast. The last syllables of the yes / no questions show longer and with higher intensity than the declarative sentences.
