Nonlinear Spectral Subtraction Method for elimination of Aircraft Engines Noise from degraded Speech Signals
The spectral subtraction is one of the best methods for elimination of approximate cyclical engines noise from degraded speech signal. Here we turn to research about the nonlinear spectral subtraction method and its improved model. After studying the nonlinear method we turn to this method that whether it can improve the quality of enhanced speech signal, propose the short-time spectral subtraction, which needs two inputs. The main input is containing the voice that is corrupted by noise. The other input (noise reference input) contains noise related in some way to that of the main input (background noise). Then use the main inputs frequency spectrum subtract the other inputs frequency spectrum. The results of experiment have proved its effective.
