Abstract

U ovom su se istraživanju analizirale frekvencije formanata kao akustički korelati
varijabilnosti hrvatskih vokala. Glavni cilj rada bio je ustanoviti utječe li na varijabilnost
vokala više konsonantska okolina vokala ili biomehaničke karakteristike govornika. U
istraživanju je sudjelovalo petnaest (15) odraslih govornika hrvatskog jezika ženskoga spola.
Govorni materijal sadržavao je 20 značenjskih riječi koje su sadržavale pet hrvatskih vokala u
četiri različite konsonantske okoline. Za svakog su ispitanika formulom standardne devijacije
izračunate dvije vrste varijabilnosti – koartikulacijska varijabilnost vokala u različitim
konsonantskim okolinama i biomehanička varijabilnost vokala kod ponavljanja istog vokala u
istim konsonantskim okolinama. Pretpostavka rada bila je da će biomehanička varijabilnost
biti jednaka koartikulacijskoj budući da još uvijek ne postoje dokazane biomehaničke razlike
koje ukazuju da su neki vokali varijabilniji od drugih. Rezultati su pokazali da je varijabilnost
vokala izraženija u ponavljanju istih vokala u istim konsonantskim okolinama, odnosno da na
varijabilnost više utječu biomehničke karakteristike govornika. Kod 13 od 15 ispitanika
biomehanička varijabilnost bila je izraženija od koartikulacijske, a kod 2 ispitanika
varijabilnosti su bile podjednake.

Abstract (english)

The goal of this master thesis and its research was to analyze the formant frequencies as
acoustic correlates of the variability of Croatian vowels. The main goal was to
determine whether vowel variability is influenced more by the consonantal environment or
the speaker's biomechanical characteristics. 15 female adult speakers of the Croatian language
participated in the research and the speech material contained 20 words with meaning that
contained five Croatian vowels, in four different consonant environments. Two types of
variability were calculated for each respondent using the standard deviation
formula: coarticulation variability of vowels in different consonant environments and
biomechanical variability of vowels when repeating the same vowel in the same consonant
environments. The main assumption of the work was that biomechanical variability will be
equal to coarticulation since there are still no proven biomechanical differences that indicate
that some vowels are more variable than others. The results showed that the variability of the
vowels is more significant in the repetition of the same vowels in the same consonant
environments. In 13 out of 15 total subjects, biomechanical variability was more significant
than coarticulation, and in 2 subjects the variability was equal.
