The problem of clustering speakers by their voices is addressed. With the mushrooming of available speech data from television broadcasts to voice mail, automatic systems for archive retrieval, organizing and labeling by speaker are necessary. Clustering conversations by speaker is a solution to all three of the above tasks. Another application for speaker(More)
New methods for speaker veriication that address the problems of limited training data and unknown telephone channel are presented. We describe a system for studying the feasibility of telephone based voice signatures for electronic documents that uses speaker veriication with a xed test phrase but very limited data for training speaker models. We examine(More)
A n o v el approach to scoring Gaussian mixture models is presented. Feature vectors are assigned to the individual Gaussians making up the model and log-likelihoods of the separate Gaussians are computed and summed. Furthermore, the log-likelihoods of the individual Gaussians can be decomposed into sample weight, mean, and covariance log-likelihoods.(More)
We present a ne-grain parallel processor architecture which considers particularly the requirements dened by future 3-dimensional (3D) stacked optoelectronic devices. The architecture concept is well-suited for novel detector arrays which are exploited in data communication applications based on high-speed VCSEL photonic interconnects as well as for optical(More)
The efficient and fast processing of path planning algorithms based on stencil codes is a great challenge. On the one hand, these iterative approaches are advantageous because of their regular processing pattern and the characteristic to avoid problems of other path planning methods, like local minima in potential field algorithms. On the other hand, they(More)
This paper presents an advanced analysis of numerical coupled 1D / 3D simulation models in the field of building energy supply systems. Here, the 1D models are described in Modelica, which is a component-oriented modelling description language for DAE (Differential-Algebraic-Equation)-systems. The 3D simulation models are described with the CFD(More)
