Development of a (silent) speech recognition system for patients following laryngectomy

The paper presents the first description of a unique concept in speech restoration, based on an entirely novel technique for monitoring articulator motion during speech, subsequently named Permanent Magnet Articulography (PMA). It overcomes significant problems with other approaches to this problem. An important finding is that to recognise speech, it is not necessary to measure the Cartesian positions of the articulators but simply to learn the nonlinear mapping between articulator motion and speech features. The paper attracted significant attention from leading international ‘silent speech’ groups, leading to joint publications (http://www.sciencedirect.com/science/article/pii/S0167639309001307) and collaborative research (e.g. Marie Curie Initial Training Network proposal).
