Dr. Marcel

On May 21, 2012 Marcel Kockmann, currently working for www.voicetrust.com, defended his thesis „Subspace modeling of prosodic features for speaker verification“.

The thesis investigates into speaker verification by means of prosodic features. This includes an appropriate representation of speech by measurements of pitch, energy and duration of speech sounds. Two diverse parameterization methods are investigated: the first leads to a low-dimensional well-defined set, the second to a large-scale set of heterogeneous prosodic features. The first part of this work concentrates on the development of so called prosodic contour features. Different modeling techniques are developed and investigated, with a special focus on subspace modeling. The second part focuses on a novel subspace modeling technique for the heterogeneous large-scale prosodic features.

Congratulations to Marcel!
