Abstract (in Japanese) (See Japanese page) 
(in English) Spectral suppression is a well known technique for speech noise reduction in the frequency domain.
In this paper, we introduce a frequency domain super-resolution method to a spectral suppression method.
The super resolution concentrates the speech energy to few frequency bins.
It is expected that the speeches and noise components are well separated by the super-resolution.
We thus introduce the super-resolution to the spectral suppression to improve the noise reduction capability.
Finally, we evaluated the spectral suppression with the super resolution in view from the noise reduction and the speech preservation.
