Abstract
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.

A linear discriminant analysis apparatus for noisy environments, the apparatus comprising:
- 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.
A linear discriminant analysis method for noisy environments, the method comprising:
- a first step of, when voice is inputted, creating various noise environment models from the inputted voice;
- a second step of creating linear transformation matrices at each of the created noise environment models;
- and
- a third step of estimating a noise model using the linear transformation matrices created in the second step, and creating a new linear transformation matrix.
