Linear discriminant analysis apparatus and method for noisy environments

摘要

A linear discriminant analysis apparatus and method for noisy environments is provided. The apparatus includes: a noise environment model creator for creating various noise environment models from an input voice; a linear transformation matrix creator for creating linear transformation matrices from and at each of the created noise environment models; and a noise model estimator for estimating a noise model using the created linear transformation matrices, and creating a new linear transformation matrix.
