Of the invention one of sound detection system searches for a part and target sound signal of storage voice signal, and the voice signal that a storage feature is stored from sequence data is calculated including storage feature calculation portion; Purpose feature calculation portion calculates signal of the target signature from time series data target sound; Storage characteristic area selected section corresponds to that selection element statistics and is greater than threshold value from storage feature and calculates storage article selection feature and generate from selected element; Target area selected section corresponds to the statistic of that selection elemental characteristic more than the purpose area selection feature that threshold value is made of from purpose feature the element selected; And feature comparison portion, regional choice feature to storage and compare similarity between the two segment target and storage area selection feature.
