Speech Signals Enhancement Using LPC Analysis based on Inverse Fourier Methods
Mostafa Hydari, Mohammad Reza Karami, Ehsan Nadernejad · 2009
This paper, proposes a new methods for speech Signal enhancement based on spectral subtraction, Inverse Fourier Transform. We use the Linear Predicative Coding (LPC), VAD analysis, and Voice / Unvoice (V/UV) detector for noise estimation and extraction, then we compare the proposed method with the previous ones and are able to recover the speech signal much better than the previous methods. Also, good results have been achieved in the auditory tests.
