Abstract
A method of and apparatus for detecting noise are provided. The method of detecting noise includes: receiving an input of a voice frame and converting the voice frame into a filter bank vector; converting the converted filter bank vector into band data; calculating a weight Gaussian mixture model (GMM) for each band by using the converted band data; and detecting noise in the voice frame based on the calculation result.
Claims10
A method of detecting noise comprising:
- receiving an input of a voice frame and converting the voice frame into a filter bank vector;
- converting the converted filter bank vector into band data;
- calculating a weight Gaussian mixture model (GMM) for each band by using the converted band data and filter bank order;
- and
- detecting noise in the voice frame based on the calculation result
- wherein in the converting of the converted filter bank vector into band data, the filter bank vectors for the entire frequency bands of the voice frame are converted into data for respective bands.
