The effect of formant trajectories and phoneme durations on vowel intelligibility
We examined how much listeners can benefit from listening to “clear” (CLR) speech compared to “conversational” (CNV) speech, both spoken at different speaking rates. Vowe...

A regularized kernel-based approach to unsupervised audio segmentation
We introduce a regularized kernel-based rule for unsupervised change detection based on a simpler version of the recently proposed kernel Fisher discriminant ratio. Compared to ot...

Voronoi cell shaping for feature selection with discrete HMMs
In this paper, we introduce a novel vector quantization (VQ) scheme for distributing the quantization error equally among the quantized dimensions. Afterwards, the proposed VQ sch...

Combined image plus depth seam carving for multiview 3D images
Multiview 3D displays have to multiplex a set of views on a single LCD panel. Due to this, each view has to be downsampled by a considerable amount leading to loss of details. In ...
