METHOD AND DEVICE FOR FRQUENCY-SELECTIVE PITCH EXTRACTION OF SYNTHETIC SPEECH Russian patent published in 2008 - IPC G10L19/14 G10L21/02 

Abstract RU 2327230 C2

FIELD: acoustics.

SUBSTANCE: invention pertains to the method and device for subsequent processing of a decoded sound signal. The decoded signal is divided into a set of signals at frequency sub-ranges. Subsequent processing is done to at least, one of the signals in the frequency sub-ranges. After processing of at least one signal from the frequency sub-ranges, the signals from the frequency sub-ranges are summed up to form an output decoded sound signal, subject to the next processing. In that way, processing is localised in the necessary sub-range or sub-ranges, leaving the other sub-ranges practically unchanged.

EFFECT: increased perceptible quality of the decoded sound signal.
