Patent ID: 8504360

Claim:
A method of automatic sound recognition, comprising: providing a training database comprising a number of models, each model representing a sound element in the form of a binary mask comprising binary time frequency (TF) units which indicate energetic areas in time and frequency of the sound element in question, or of characteristic features or statistics extracted from the binary mask; providing an input signal comprising an input sound element; estimating with a processor the input sound element based on the models of the training database to provide an output sound element; providing an input set of data representing the input sound element in the form of binary time frequency (TF) units which indicate the energetic areas in time and frequency of the sound element in question, or of characteristic features extracted from the binary mask; and providing binary masks for the output sound elements by modifying the binary mask for each of the corresponding input sound elements according to the identified training sound elements and a predefined criterion.
