成果简介	NOVELTY - The device has an analog-to-digital signal converter (1) constructed based on isolation of segments of speech processing and based on analysis of correlation dependencies in a speech signal. Sequentially connected units calculate dispersion of the input signal such that classification and segmentation of the speech signal are additionally introduced with a series-connected noise variance calculation unit (2.1). A threshold value calculation unit (3) calculates averaging interval value with an input. An output of the analog-to-digital converter is connected to an input of a noise variance calculation unit and to an input of a speech signal segmentation unit (6). USE - Device for isolating segments of speech processing on a single-chip computer in a speech signal coding and processing system i.e. biometric speaker recognition system. ADVANTAGE - The device increase probability of correct segmentation of a speech signal under noise conditions and expansion of the scope of application due to the use of differences in the energy properties of the speech signal and noise. DESCRIPTION OF DRAWING(S) - The drawing shows a block diagram of a device for isolating segments of speech processing. 1Analog-to-digital signal converter 2.1Series-connected-noise variance calculation unit 3Threshold value calculation unit 4Averaging interval value calculation unit 5Classification unit 6Speech signal segmentation unit
