METHOD AND DISCRIMINATOR FOR CLASSIFYING DIFFERENT SIGNAL SEGMENTS Russian patent published in 2014 - IPC G10L25/00 

FIELD: information technology.

SUBSTANCE: method and discriminator for classifying different segments of a signal designed to classify different segment of a signal which comprises segments of at least a first type and second type, e.g. musical and speech segments, a short- term classification (150) signal based on at least one short-term feature extracted from the signal and a short- term classification result (152); a long-term classification (154) signal based on at least one short-term feature and at least one long-term feature extracted from the signal and a long-term classification result (156). The short-term classification result (152) and the long-term classification result (156) are combined (158) to provide an output sampling signal (160) indicating whether a segment of the signal is of the first type or of the second type.

EFFECT: providing an improved approach to differentiate segments of a different type in a signal while keeping low any delay caused by the discriminator.
