Abstract
Official abstract text for this publication.
Disclosed is the system and method to remove noises in voice signals in a voice communication. The at least one embodiment of the present disclosure performs a spectral subtraction (SS) for voice signals based on a gain function by a spectral subtraction apparatus, performs clustering of voice signals consecutive on a frequency axis of a spectrogram for the voice signals in which the spectral subtraction has been already performed to designate one or more clusters, and extracts musical noises by determining continuity of each of the designated clusters on the frequency axis and a time axis of the spectrogram to extract musical noises.
First claim
Opening claim text (preview).
What is claimed is: 1. A noise removing system in a voice communication, comprising: a spectral subtraction apparatus configured to perform a spectral subtraction (SS) for voice signals; and a noise removing apparatus configured to perform clustering of the voice signals, for which the spectral subtraction has been performed and which are consecutive on a frequency axis of a spectrogram, to designate one or more clusters, and determine continuity of each of the designated clu…
