Abstract: The present disclosure provides a measurement method and system based on image electroencephalogram sensitivity data for a built environment dominant color, and relates to the field of urban quality measurement. The measurement method based on image electroencephalogram sensitivity data for a built environment dominant color includes acquiring electroencephalogram data corresponding to a built environment image sample; calculating an environment dominant color sensitivity on the basis of the electroencephalogram data; extracting a dominant color feature parameter according to the built environment image sample; constructing a built environment dominant color measurement model, and training same by taking sensitivity data and a dominant color feature as an input; and inputting an environment image to be analyzed into a trained model, so as to obtain a predicted dominant color sensitivity result.

Abstract: An embodiment of the present disclosure discloses a method and a system for speech recognition. The method comprises steps of intercepting a first speech segment from a monitored speech signal, analyzing the first speech segment to determine an energy spectrum; extracting characteristics of the first speech segment according to the energy spectrum, determining speech characteristics; analyzing the energy spectrum of the first speech segment according to the speech characteristics, intercepting a second speech segment; recognizing the speech of the second speech segment, and obtaining a speech recognition result. The method solves the problems of single recognition function and low recognition rate of the prior art in the off-line state.
