Noise reduction of recorder speech in an NMR imaginer during phonation for 3D vocal tract modeling
Original language description
The paper presents two methods of noise reduction of recorded speech signal during phonation for the human vocal tract modeling in an NMR imaginer. The noise is mainly produced by gradient coils, have a mechanical character, and can be processed in spectral domain. Our first noise reduction method use real cepstrum limitation and clipping the ?peaks corresponding to the harmonic frequencies of mechanical noise. The second method is coming out from substation of the short-time spectra of two signals recorded withal: the first includes speech and noise, and the second is consisted of the noise only.
