Glottalization in the combination with non-syllabic prepositions in the Czech speech of Russian speakers

Glottalization, as significant irregularity of glottal pulsing, fulfils a number of linguistic functions and can occur in various contexts. This paper examines the rate of vowel-related glottalization of non-syllabic prepositions when native Russian speakers read Czech speech. In Czech, just like in other languages there is a relatively high frequency of glottalization. The purpose of this study is to examine the factors that could influence it. The speakers produced a short read text which contained 59 potential neslabičné prepositions where glottalization could occur in standard pronunciation. The basic set of the perceptual analysis and statistical processing consisted of 582 items. The rate of glottalization in individual speakers ranged from 0 % to 90 % , where the average volume is regulary based at 49 %. Statistical significance of differences in the frequency of the analyzed groups created on the basis of monitored aspects were calculated using the chi-square test
