Abstract

Ovaj rad bavi se ispitivanjem odnosa percepcije glazbe i razumljivosti govora u djece s kohlearnim implantima. U ispitivanju je sudjelovalo 4 djece s prirođenim oštećenjem sluha. Postavljena je pretpostavka kako je razumljivost govora ispitanika povezana s njihovim vještinama percepcije glavnih obilježja glazbe.
U ispitivanju su korišteni zadaci koji su snimljeni uz pomoć profesionalnih glazbenika, a po uzoru na Abdi (2001) te su formirane varijable Timbar, Tonska visina, Melodijska linija i Ritam. Za ispitivanje razumljivosti djece s kohelarnim implantima iskorišten je odlomak teksta pripovijetke koji je minimalno prilagođen kako bi najbolje odgovarao učestalosti glasova u hrvatskom standardnom govoru te s obzirom na primjerenost razine zahtjevnosti za čitanje od strane gluhog školskog djeteta. Snimke čitanja su prezentirane studentima završne godine Logopedije, koji su ih potom ocijenili te je formirana varijaba Razumljivost govora.
Uvidom u pojedinačne odgovore ispitanika,vidljivo je kako sudionici istraživanja imaju najviše teškoća u percepciji melodijske linije i timbra, dok najmanje teškoća pokazuju u percepciji ritmičkih elemenata. Također, statističkom analizom utvrđena je korelacija između glazbenih sastavnica timbra i visine te timbra i melodijske linije. Ocjene razumljivosti govora analizom rezultate pokazale su se u značajnoj mjeri povezane s percepcijom melodije i timbra, što je u skladu s brojnim stranim istraživanjima.
S obzirom na ustanovljenu značajnu pozitivnu povezanost između percepcije pojedinih sastavnica glazbe i ocjene razumljivosti govora, za logopedsku je struku uputno nastaviti istraživanja ove teme u smjeru ispitivanja uzročno-posljedične veze između sustavnog izlaganja pedijatrijskih korisnika kohlearnog implanta glazbi i razumljivosti njihovog govora.

Abstract (english)

The aim of this study is to investigate the relation between the speech intelligibility and music perception in four congenitally deaf children with cochlear implants. It was hypothesized that there is a connection between their music perception abilities and speech intelligibility.
Various music tasks were recorded with the help of professional musicians, modeled on Abdi (2001), and the variables Timbre, Tonal height, Melody line and Rhythm were formed. The speech intelligibility of children with cochlear implants was examined trough the readings of the short story, minimally adapted to best match the frequency of sounds in the Croatian standard speech and the appropriateness of the level of readability of deaf children. The readings were recorded and presented to the students of the final year of Maters's Program in Speech Language Pathology, who then rated children’s speech intelligibility.
From the individual success on the music tasks it is evident that for the children with cochlear implants perception of the melodic line and the timbre was the most problematic, while the perception of the rhythmic elements was the least problematic. Also, statistical analysis showed a strong correlation between the timbre and the tonal height, and between the timbre and the melodic line. The mean ratings of speech intelligibility were positively correlated with the success in the perception of the melody and the timbre, which is consistent with numerous foreign studies.
Considering the significant positive correlation between the perception of music components and the speech intelligibility, it is advisable for speech language pathologist to continue researching this topic in the direction of examining the causal relationship between the systematic presentation of music for the pediatric cochlear implant users and the intelligibility of their speech.
