Speech recognition in neural architecture
(Data based Modelling and Neuroinformatics)

The machine recognition of human speech still poses a challenge. In the past years, biologically motivated concepts for the preprocessing of acoustic signals and the for pattern recognition have been developed at BMO. Within these concepts, a Bayesian Classificator, that gives a probabilistic statement on the affiliation of acoustic patterns to phonem classes, plays a key role in the neural implementation.

Currently, we are working on the identification of word sequences within fluently spoken speech characterized by segmented sequences of phoneme hypotheses vectors
