Contacting me by mail

I am sorry to report that email communication becomes increasingly challenging because of the large numbers of incoming mails (average response rate ~25%). As a rule of thumb: if you do not receive an answer within the same week, the chance that you will drifts towards zero. I am very unhappy about this situation and wish to apologise sincerely for the trouble this may cause.

Resending your mail sometimes helps but should you wait for an urgent reply please contact Ms Tamar Tolcachier (see right teaser). Instead of writing a mail you may alternatively book a phone or office appointment through her.

Interests: I am interested in a wide variety of phenomena related to human and machine communication with speech. Most of my research has to do with speaker specific (indexical) information in the speech signal and how humans and machines can use such information to recognize individuals. While I worked on the applications of such knowledge in applied areas such as forensic phonetics, I recently became more and more interested in the interaction between indexical and linguistic information in human communication.

Employment: Since August 2010 I am researching and teaching Phonetics and Speech Sciences at Zurich University (UZH) in Switzerland and occasionally work as an expert witness in forensic phonetics on a freelance basis. Previously I was lecturer in phonetics and speech sciences at University College London (2003-2010) and worked as a consultant and project manager in digital signal processing projects for iQuest Ltd. London. Before that I had research assistant posts at Bonn (2002-3) and Jena Universities (2000-2). I also worked regularly as a guest lecturer at UIMP in Madrid, City University London and Greewich University. In 1999 I was an assistant teacher for German at the Icelandic High School Menntaskólinn í Reykjavík.

Education: I have a PhD in Phonetics and Communication Sciences from Bonn University (with Wolfgang Hess and Petra Wagner) for which I studied the relationships between speech rate and speech rhythm. I have an MA in Phonetics and Linguistics from Trier University focussing on Forensic Phonetics (native language influences on speaker identification abilities by naive listeners). During my studies I spent a year in Santiago de Compostela/Spain (1995) studying the phonetics of Galician, a year at Edinburgh University (1996/97) studying phonetics, digital signal processing and Scottish Gaelic, and I was a guest student in the Phonetics Department at Saarbrücken University (1998).
