Currently, I am working the the Infrastructure Project of the SFB 732.  We are responsible for a number of aspects, all centering around the data collected in the SFB. Within the project, one of the topics I concerend with is bringing together the output of the text-based tools and annotations available at the IMS with our speech data (and its automatic or manual annotations). To this end, I support my incredibly clever colleagues Kerstin Eckart and Markus Gärtner, who are computer geniuses (and much more), by bringing phonetic expertise into the team.

Markus developed a powerful search tool for linguistic data, ICARUS. Its prosody module, which we worked on, recently, brings together output from parsers, taggers, human annotators, ... with the acoustics of intonation. We used a parametric intonation model, PaIntE, to make characteristics of the tonal contour available in the search. For instance, you can search for "prototypes" of accents (and instances similar to the prototype) in specific configurations of the linguistic context. You can directly play the utterances, see the PaIntE values, export the result of your search, and in the future you will also be able to correct annotations or change other aspects. 

From July 2006 to July 2014 I worked in the project Incremental Specification of Focus and Givenness in a Discourse Context (A1) of the SFB 732  investigating the semantic-prosodic interface. We annotated both information structure and intonation, to build up corpora for statistical analyses of correlations between these two aspects. For instance, we released the DIRNDL database.  Moreover, we aimed to intergrate pitch accents as well as their discourse context into a usage-based model of intonation. We examined the effects of lexical frequency and frequency of contextual configurations on pitch accent realisations. The results we gatherd present a challenge for traditional autosegmental theories of intonation while a usage-based account predicts them correctly.

From July 2010 to October 2011 I also worked in a DFG-project on Prosodic Phrasing that investigates the status of prosodic phrasing in auditory and visual sentence processing. Prosodic phrase boundaries can influence the syntactic structure as well as the processing of argument status. One aim of the project is to identify the exact timing and functional make-up of prosody processing by measuring event-related potentials (ERPs). However, we also looked at phrasing in a corpus-phonetic approach. Specifically, we looked at the idea of prosodic balance, that is, the idea that speakers tend to produce prosodic phrases of equal structure.




Research Intrests

I love digging into data and finding relationships between different aspects of Speech and language. When intonation is involved, I am most happy :-), but I am also intersted in other aspects of prosody, in prominence, segmental features and also in extra-linguistic features.

My PhD thesis was concerned with  the question whether intonation can be lexicalised, and how intonation and the context in which tonal events occur can be modelled in a usage-based theory of speech production and perception.  I looked at effects of word frequency on pitch accent shape. They exist! The results fit well with the idea of Exemplar Theory, therefore I outlined how an existing exemplar model can be modified to deal with such phenomena. Now I am keen to find out more about how the production and perception of intonation works and how models of language and speech processing could integrate intonation...
