I am currently Professor in Phonetics at the Department of Linguistics, Stockholm University, Stockholm, Sweden. Previously, I was a researcher in the Speech group at the Department of Speech, Music and Hearing at KTH in Stockholm. I received my Ph.D. in Phonetics from Umeå University (2002) and was a postdoc at TeliaSonera Sweden (2005).

My main interest is interactional aspects of spoken face-to-face communication. My work aims to combine linguistic knowledge with speech technology to describe and model interactional behaviour, and in use such models for generation and understanding of interactional behavior in speech technology.

The rhythm of conversation
01/01/2010 - 31/12/2012
Samtalets rytm ska undersöka företeelser som bara finns i mänskliga samtal och inte i andra former av tal. Framför allt handlar projektet om hur de som deltar i samtalet gemensamt reglerar det -- hur de vet vad som är ett lämpligt ställe att ta ...

Collaborating with

Zora, Hatice
In my PhD research project, I investigate the perceptual correlates of word stress and their contribution to lexical access by carrying out electrophysiological measurements of brain activity (EEG/ERP). The objective is to indicate the activation of long-term memory traces for le...
