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.
Claims12
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
- detecting noise in the voice frame based on the calculation result.
The method of claim-1, wherein in the calculating of the weight GMM for each band, the weight GMM for each band is calculated by applying a weight for the band to a GMM for the band which is trained in advance.
An apparatus for detecting noise comprising:
- a filter bank analysis unit receiving an input of a voice frame and converting the voice frame into a filter bank vector;
- a band data converting unit converting the converted filter bank vector into band data;
- a band weight GMM calculation unit calculating a weight GMM for each band by using the converted band data;
- and
- a noise detection unit detecting noise in the voice frame based on the calculation result.
