METHOD FOR RECOGNIZING WORDS IN CONTINUOUS SPEECH Russian patent published in 2007 - IPC G10L15/02 

FIELD: automatics and computer science, possible usage in systems for controlling technological, home appliance and other equipment, in automatic reference systems, automatic translation systems, speech understanding systems.

SUBSTANCE: in accordance to method, during pronouncing of speech phrase, taken periodically are selections of acoustic signal of this phrase, digitized with given quantization frequency, in fixed time interval or based on combination of selection, functional is calculated, determining current acoustic condition, while received series of current acoustic conditions is used for restoration of series of words (working hypothesis), pronounced in original speech phrase, for that purpose lexical decoding network is used, which sets rules of order of standard acoustic conditions in a language. Working hypothesis is found, being optimal in terms of maximal match thereof with original speech signal, which is ensured by usage of movable marker algorithm, while working hypothesis is restored from marker, which at this time moment is at end vertex of lexical decoding network.

EFFECT: increased precision of words recognition in continuous speech.
