A conditional model for triggering understanding actions in a speech understanding system
A conditional model is introduced for triggering understanding actions that correct errors of frame hypothesization and composition. Experimental evidence is provided using the Fr...

Direction-of-arrival estimation using acoustic vector sensors in the presence of noise
A vector-sensor consisting of a monopole sensor collocated with orthogonally oriented dipole sensors can be used for direction-ofarrival (DOA) estimation. A method is proposed to ...
