Abstract
The present invention relates to an apparatus and a method for removing ambient noise from a speech waveform by using a band-pass filter and deep learning, wherein the apparatus and method are implemented to remove ambient noise from a speech waveform combined with the ambient noise and extract only a clean speech waveform so that a human's speech can be easily understood.
Claims16
An apparatus for removing ambient noise from a speech waveform, the apparatus comprising:
- an ambient noise removal unit configured to receive a first speech waveform as an input, remove noise through filtering and deep learning, and then output a fourth speech waveform;
- and
- a deep learning training unit configured to calculate deep learning weights that are used in deep learning through the deep learning training and to provide the deep learning weights to the ambient noise removal unit.
