TAILIEUCHUNG - Báo cáo khoa học: "Frequency Matters: Pitch Accents and Information Status"

This paper presents the results of a series of experiments which examine the impact of two information status categories (given and new) and frequency of occurrence on pitch accent realisations. More specifically the experiments explore within-type similarity of pitch accent productions and the effect information status and frequency of occurrence have on these productions. The results indicate a significant influence of both pitch accent type and information status category on the degree of withintype variability, in line with exemplartheoretic expectations. . | Frequency Matters Pitch Accents and Information Status Katrin Schweitzer Michael Walsh Bernd Mobius Arndt Riester Antje Schweitzer Hinrich Schutze University of Stuttgart Stuttgart Germany firstname . surname @ Abstract This paper presents the results of a series of experiments which examine the impact of two information status categories given and new and frequency of occurrence on pitch accent realisations. More specifically the experiments explore within-type similarity of pitch accent productions and the effect information status and frequency of occurrence have on these productions. The results indicate a significant influence of both pitch accent type and information status category on the degree of within-type variability in line with exemplar-theoretic expectations. 1 Introduction It seems both intuitive and likely that prosody should have a significant role to play in marking information status in speech. While there are well established expectations concerning typical associations between categories of information status and categories of pitch accent . rising L H accents are often a marker for givenness there is nevertheless some variability here Baumann 2006 . Furthermore little research has focused on how pitch accent tokens of the same type are realised nor have the effects of information status and frequency of occurrence been considered. From the perspective of speech technology the tasks of automatically inferring and assigning information status clearly have significant importance for speech synthesis and speech understanding systems. The research presented in this paper examines a number of questions concerning the relationship between two information status categories new and given and how tokens of associated pitch accent types are realised. Furthermore the effect of frequency of occurrence is also examined from an exemplar-theoretic perspective. The questions directly addressed in this paper are as follows 1. How are .
