This paper reports our recent efforts to develop a uni£ed, non-linear, stochastic model for estimating and removing the effects of additive noise on speech cepstra. The complete system consists of prior models for speech and noise, an observation model, and an inference algorithm. The observation model quanti£es the relationship between clean speech, noise, and the noisy observation. Since it is expressed in terms of the log Melfrequency £lter-bank features, it is non-linear. The inference… CONTINUE READING
