Audible signal emphasis device - Mitsubishi Electric Corporation

Title:

Audible signal emphasis device

Document Type and Number:

Japanese Patent JP6279181

Kind Code:

B2

Abstract:

A first signal weighting processor outputs a weighted signal obtained by performing a weighting on part of an input signal representing a feature of a target signal included in the input signal. A neural network processor outputs an enhancement signal for the target signal by using a coupling coefficient. An inverse filter cancels the weighting on the feature representation of the target signal in the enhancement signal. A second signal weighting processor outputs a weighted signal obtained by performing a weighting on part of a supervisory signal representing a feature of a target signal. An error evaluator output a coupling coefficient to have a value indicating that a learning error between the weighted signal output from the second signal weighting processor and the output signal of the neural network processor is less than or equal to a set value.
