METHOD AND DISCRIMINATOR FOR CLASSIFYING DIFFERENT SEGMENTS OF A SIGNAL

摘要

For classifying different segments of a signal which comprises segments of at least a first type and second type, e.g. audio and speech segments, the signal is short- term classified (150) on the basis of the at least one short-term feature extracted from the signal and a short- term classification result (152) is delivered. The signal is also long-term classified (154) on the basis of the at least one short-term feature and at least one long-term feature extracted from the signal and a long-term classification result (156) is delivered. The short-term classification result (152) and the long-term classification result (156) are combined (158) to provide an output signal (160) indicating whether a segment of the signal is of the first type or of the second type.
