1. ARCs and their functions in discourse
0. Global project and methodology
• Starting point: Loock’s (2003, 2005, 2007) taxonomy of ARCs and their discourse functions:
• Aim: relate discourse functions/structure and prosody
• Study of Appositive Relative Clauses in English (ARCs, see 1)
CONTINUATIVE ARC (3)
It makes narrative time move forward. The events are
shown in a sequence and a causal link may exist.
(1) The students, who like linguistics, also like translation.
• 2-step methodology:
• Discourse annotation: discourse function, information status of ARC and MC, syntactic characteristics
• Prosodic annotation: semi-automatic analysis of the corresponding recordings using original scripts with
Praat (cf. Boersma & Weenink 2006)
RELEVANCE ARC (2)
SUBJECTIVITY ARC (4)
The aim is to optimize the relevance of the antecedent
and/or the subject-predicate relation within the MC.
The ARC conveys information that is explicitly subjective
and allows for a rupture between two levels:
ARC
• Corpora:
• Aix-MARSEC (cf. Auran, Bouzon & Hirst 2004)
• IViE (cf. Grabe & Post 2002)
• ICE-GB (cf. Greenbaum 1996)
The referential level (MC)
The interpretative level (ARC)
The antecedent, in spite of its referential stability, is not
sufficiently determined for at least some of the
addressees to be used alone in discourse.
EXPLOITATION OF THE INTERCLAUSAL LINK
The inter-clausal link between the MC and
the ARC is exploited to bring a new
perspective on the contents of the MC.
2. Prosodic analysis
• Prosody as a macro-system:
(2) he was convinced # the battle # for the hearts # and minds of the people # was being won # especially #
among the Ovambo # who form the majority # of SWAPO's support
• tonal aspects (tone and intonation, in relation with speech melody)
• temporal aspects (unit durations and speech rate)
(3) the first book he took from the library was Darwin's # Origin of Species # which inspired him with the dream of
becoming a geologist
• intensity (one of the major correlates of loudness)
• voice quality (in relation with spectral characteristics of the speech signal)
• Representation levels (Hirst et al. 2000):
(4) Israelis # have sympathy and liking for Americans # which is just as well # since the country is swarming # with
transatlantic visitors
• 2 prosodic dimensions:
• acoustic level: physical characteristics of the
speech signal (F0, raw durations, dB)
Linear
• phonetic level: retains only linguistically
significant elements (low-level physical
constraints factored out: MoMel modelling, ztransformed durations)
Orthogonal
• Differences in the hierarchisation of the informational contents (ARC vs. MC):
• Relevance/subjectivity: MC = foreground vs. ARC = background
• Continuative: informational contents on the same level (narrative dynamism traditionally restricted to independent clauses;
cf. Depraetere 1996)
=> Are continuatives independent clauses?
(cf. Ross 1967, Emonds 1979, McCawley 1982, Fabb 1990 among others, who express this idea for ARCs as a whole.)
• phonological levels (surface and deep): discrete
and abstract coding
Level
250
=> Prosodic investigation: are ARCs realized with the intonation contour of independent clauses or parentheticals?

• Register and intensity spans + speech rate  classical IUs realizing independent clauses
• to be linked with the possibility for ARCs to:
• have the syntactic behaviour and the semantic interpretation of independent clauses
• convey independent speech acts (cf. Emonds 1979, McCawley 1982 among others)
• Relevance vs. Subjectivity ARCs:
6. Conclusion
• Apparent correlation between discourse functions and prosody
• Discourse discontinuity marking through high onset values for both types
• Some prosodic characteristics atypical of appositions in general
• Subjectivity ARCs display even stronger discontinuity ↔ more important rupture with the discourse
topic (cf. shift between the referential and interpretative levels; see frame 1)
• Differences among ARC types: Subjectivity ARCs display prosodic rupture cues, on a par with the
peripheral information which they convey
More peripheral information conveyed by subjectivity ARCs (non-topical comment or judgement)
• Lower intensity level values for Subjectivity ARC: strategy used by the speaker to induce the perception
of intermediate levels between otherwise discrete categories such as continuity/discontinuity,
subjectivity/objectivity, etc. (conflicting prosodic characteristics for subjective episodes; cf. Di Cristo et al.
2004)
• Speech rate differences need further investigation (the great majority of subjectivity ARCs qualifies
sentential antecedents (cf. Loock 2007): parameters difficult to separate)
• Further investigation:
• The respective roles of the syntactic status of the antecedent (nominal vs. sentential) and of the ARC
type, particularly with relation to speech rate, need to be closely analysed.
• Prosodic characteristics of Continuative ARCs: typical of subordinate or main clauses?
Problem: availability of acoustically exploitable unscripted/spontaneous data
