Project summary - first phase:

In intonational phonology it is generally agreed that tones are not simply concatenated like beads on a string. However, there is no consensus as to how these tones are phonologically structured. Here we propose to develop a model of tonal representation using evidence from tune-text synchronisation within and across three varieties of German (those spoken in Vienna, Düsseldorf and Kiel).

This involves the alignment of tonal targets in the form of fundamental frequency (F0) events (minima and maxima) with landmarks relating to the sounds spoken, which serve as anchors for the targets. Evidence for tonal structure will be gained from production data at the acoustic and articulatory levels and from perception experiments. In the acoustic studies, landmarks are taken to be acoustically defined onsets and offsets of vowels and consonants; in the articulatory study landmarks are articulatory minima and maxima (measured using electromagnetic articulography) correponding to vocalic and consonantal gestures. The key to how the underlying tones relate to each other and to the text which carries them is provided by examining which alignment properties are robust across a variety of conditions, in particular across different articulation rates, levels of emphasis, and syllable structures. Robustness of alignment will reveal those aspects of alignment which are a result of phonetic implementation and those which should be interpreted as part of the phonology of a particular language variety. The gestural approach will additionally provide insights into laryngeal and supralaryngeal synchronisation, which will in turn contribute towards developing cognitive models of speech production.

 

Second phase:

In this second phase of the project we aim to provide a theoretical contribution towards a model of intonation structure, arguing that a number of pitch accents should be regarded as derived from an underlying representation which is not fully specified as to the association properties of certain tones.

The introduction of derived pitch accents allows us to constrain the inventory in a meaningful way. Although much can be learnt about association from examining the details of how tonal targets are aligned, an understanding of our results demands a closer look at where tonal targets are situated in the frequency domain – that is, their scaling. In a number of production and perception studies evidence from both the time and frequency domains will be used to investigate the phonological identity of pitch accents and to ascertain whether variation is phonological or phonetic.

Results will contribute to the further development of our theoretical model and to a revised version of the prosodic annotation system, GToBI. Evidence from the alignment of tonal targets with articulatory movements will be used to model the coordination between supralaryngeal and laryngeal gestures in articulatory synthesis. Our experiments will concentrate on a comparison between two varieties of German, those from Düsseldorf and Vienna.
