International Classification:

G10L 15/00
G10L 15/16
G10L 15/20

Abstract:

Method and system for processing and identifying a sub-audible signal formed by a source of sub-audible sounds. Sequences of samples of sub-audible sound patterns (“SASPs”) for known words/phrases in a selected database are received for overlapping time intervals, and Signal Processing Transforms (“SPTs”) are formed for each sample, as part of a matrix of entry values. The matrix is decomposed into contiguous, non-overlapping two-dimensional cells of entries, and neural net analysis is applied to estimate reference sets of weight coefficients that provide sums with optimal matches to reference sets of values. The reference sets of weight coefficients are used to determine a correspondence between a new (unknown) word/phrase and a word/phrase in the database.
