From science fiction to science fact: A Smart-House interface using speech technology and a photo-realistic avatar

Abstract

This paper explores the problems of speech recognition in a (sometimes) noisy environment. An adaptive acoustic beamformer is proposed based on the Griffiths-Jim method and a "hot-spot" where speech can be received within a geometric defined boundary and rejected outside of it will be shown to give a certain amount of noise immunity and improve the signal… (More)
