A Cognitive View on Prosodic Relations

Abstract

The paper presents a new F0 contour partitioning approach by using the category of prosodic relations also used by Ladd (2008) for improving the F0 contour descriptions based on phonological categories. The new approach involves a cognitive view on the low-high and high-low ’metrical’ structures of prosodic relations, by relating them to the structures of cognitive relations generated during speech object representations at the cortical level. In section 2, the paper presents the information structure model by defining the cognitive categories that describes prosodic relations of F0 contours involving their two overlapped structures and nuclear positions. CU_predicate-CU_argument and CU_theme-CU_rheme are the two structural levels of prosodic relations. The model proposes a binary-tree hierarchy to describe the articulation of prosodic relations within utterances. Two rules are formulated for the identification of nuclear constituents of prosodic relations. The utterances analysed in section 3 illustrate how prosodic and prominence relations can be identified by analysing acoustic cues of their F0 contours. Utterances correspond to English borad focus and narrow focus statements. Focus positions are deduced by only using the rule of the cognitive model.
