Although the electrolarynx (EL) provides an important means of voice reconstruction for patients who lose their vocal cords by laryngectomies, the radiated noise and additive environment noise reduce the intelligibility of the resulting EL speech. This paper proposes an improved spectrum subtract algorithm by taking into account the non-uniform effect of colored noise on the spectrum of EL speech. Since the over-subtraction factor of each frequency band can be adjusted in the enhancement process, a better noise reduction effect was obtained and the perceptually annoying musical noise was efficiently reduced, as compared to other standard speech enhancement algorithms.
