Abstract

Ovaj rad istražuje povezanost artikulacijskih i akustičkih svojstava okluziva i njihove rezistentnosti na maskiranje. Signali su bili bezznačenjske dvosložne riječi (logatomi) koje su se sastojale od bezvučnih i zvučnih hrvatskih okluziva u okruženju vokala /a/. Logatomi su snimljeni u izgovoru muškog i ženskog govornika odrasle dobi. Maska je bila širokopojasni šum raspona 18 kHz. Svaki signal maskiran je šumom intenziteta 62, 65, 68, 71, 74 i 77 dB. Bilabijalni okluzivi pokazali su se kao najrezisteniji na masku što se može pripisati zakrivljenosti tranzijenata i stabilnosti njihovih formanata. Rezistentnim se pokazao i zvučni velarni /k/. Ispitanici su u ovom istraživanju najteže prepoznavali zvučni alveolarni /d/ ženskog govornika.

Abstract (english)

This study examines the relationship between articulatory and acoustic cues of plosives and their resistance to masking. The signals used in this study were non-words containing voiceless and voiced Croatian plosives, with the vowel /a/ both preceding and following the plosives. Recordings were made by an adult male and an adult female speaker. The masking noise was a wideband noise with a frequency range of 18 kHz. Each signal was masked with noise at intensities of 62, 65, 68, 71, 74, and 77 dB. Bilabial plosives were found to be the most resistant to masking, a characteristic that can be attributed to the curvature of their transitions and the stability of their formants. The voiced velar /k/ also showed resistance to masking. In this study, participants had the greatest difficulty recognizing the voiced alveolar /d/ when spoken by the female speaker.
