pitch accent

Finally discourse and sentential occurrences were distinguishable in terms of presence or absence of pitch accent--and by type of pitch accent where accented. (Hirschberg & Litman, 1993)
Given these structures we can quantify the accuracy with which the realizer is able to reproduce the pitch accent and edge tone choices in the target sentences and compare it to the accuracy with which n-gram models predict these choices using maximum likelihood. (White, Clark & Moore, 2010)
In Pierrehumbert and Hirschberg (1990) a compositional approach to intonational meaning is proposed in which pitch accents are viewed as conveying information status such as newness or salience about the denotation of the accented items and the relationship of denoted entities states or attributes to speaker and hearer's mutual beliefs about the discourse. (Hirschberg & Litman, 1993)
Lexical items that do bear pitch accents are said to be accented while those not so marked are said to be deaccented. (Hirschberg & Litman, 1993)
Theune (2002) likewise follows Prevost's approach in her system refining the way contrast is determined in assigning pitch accents. (White, Clark & Moore, 2010)
