Professor, Department of Engineering Reykjavik University
I research speech signal processing and speech technology: how the voice source can be estimated from recorded speech, what the signal reveals about a speaker's cognitive and mental state, and how recognition and synthesis can be built for languages with limited resources — Icelandic in particular.
Analysis of the speech signal and of the voice source itself: estimating how the glottis opens and closes, separating source from filter, and characterising voice quality.
Glottal closure and opening instants
Glottal inverse filtering
Voice quality
Speech, Health and Cognitive State
Using acoustic and voice-source features to study how cognitive load and mental health conditions are reflected in speech.
Cognitive workload in speech
Depression and anxiety in speech
Speech Recognition and Synthesis
Recognition and synthesis methods that work for languages with limited data and resources, with Icelandic as the primary case.
