Prosodic disambiguation from deep syntactic structures
Philipp von Böselager, IfL Phonetik, University of Cologne Berthold Crysmann, DFKI & Saarland University Paper File |
In this paper, we report on an experiment showing how the introduction of detailed prosodic information into synthetic speech leads to better disambiguation of structurally ambiguous sentences. Using modifier attachment (MA) ambiguities and subject/object fronting (OF) in German as test cases, we show that prosody which is automatically generated from deep syntactic information can lead to considerable disambiguation effects, and can even override a strong semantics-driven bias. The architecture used in the experiment, consisting of a large-scale generator for German, a prosody module, and the speech synthesis system MARY is shown to be a valuable platform for testing hypotheses in intonation studies. | |

On the edge: Acoustic cues to layered prosodic domains

Prosodic structure encodes grouping of words into hierarchically layered prosodic constituents, including the prosodic word, intermediate phrase (ip) and intonational phrase (IP). This paper investigates the phonetic encoding of prosodic structure from a corpus of scripted broadcast news speech through analysis of the acoustic correlates of prosodic boundary and their interaction with phrasal stress (pitch-accent) at three levels of prosodic structure: Word, ip, and IP. Evidence for acoustic effects of prosodic boundary is shown in measures of duration local to the domain-final rhyme. These findings provide strong evidence for prosodic theory, showing acoustic correlates of a 3-way distinction in boundary level. | |

Minimum size constraints on Intermediate Phrases
Gorka Elordieta, University of the Basque Country Paper File Additional Files |
In Northern Bizkaian Basque (NBB), Intermediate Phrases (ips) align by default with the left edge of syntactic phrases. The main intonational cue of ips is partial pitch reset at their left edges. A minimal size constraint applies on ips occurring at the left edge of an Intonational Phrase (IP), requiring that they consist of at least two Accentual Phrases (APs). Following [9]’s idea that certain prominent positions demand augmentation, the NBB facts show that the left edge of an IP can also be a phonologically prominent position. | |
