In this study, the relation of phoneme structure and success rate of Czech texts is investigated. The study is based upon two phenomena: (1) the beauty-in-averageness effect and (2) the euphony principle.
The main objective is to examine whether one or the other prevails in the perception of written text, whether they interact in some way, or whether the phoneme structure has no major effect on the text's appeal to the readers. Several phoneme groups, both vowel and consonant, are focused on.
