Abstract :
A hybrid noise reduction method using both spectral subtraction and root cepstral subtraction procedures is applied to speech produced using an artificial larynx (electro-larynx). The noise reduction suppresses the direct path noise of the electro-larynx device and provides an improvement in mean opinion score
