Perception of Word-level Prominence in Free Word Order Language Discourse

This study examines the contribution of constituent order, prosody, and information structure to the perception of word-level prominence in Russian, a free word order language. Prominence perception is investigated through the analysis of prominence ratings of nominal words in two published narrative texts. Word-level perceived prominence ratings were obtained from linguistically naïve native speakers of Russian in two tasks: a silent prominence rating task of the read text passages, and an auditory prominence rating task of the same texts as read aloud by a native Russian speaker. Analyses of the prominence ratings reveal a greater likelihood of perceived prominence for words introducing discourse-new referents, as well as words occurring in a non-canonical sentence position, and featuring acoustic-prosodic enhancement. The results show that prosody and word order vary probabilistically in relation to information structure in read-aloud narrative, suggesting a complex interaction of prosody, word order, and information structure underlying the perception of prominence.
