Estimation method of using incremental Bayes learning ruu00ecdo

摘要

"Estimation method of ruu00ecdo using incremental Bayes learning".This is a method and apparatus calculate noise in a signal with additive noise using incremental Bayes learning.Where a prior distribution of noise with variation of time is considered and the hyperparameters (mean and variance are updated) recursively using a posterior approach for computedIn the stage of previous time. The additive noise in time domain is represented in the spectrum log or the field cepstrum before application of incremental Bayes learning.The results of both mean and variance estimates for the noise to each of the separate tables are used to implement intensification of characteristic of voice in the same spectrum - logOr the field cepstrum.
