Separation of Speech Signals for Nonlinear Mixtures

چکیده
We have proposed various procedures that are based on geometrical properties of source vectors, S (t), and of mixtures, E(t), from the hypothesis that the sources are bounded [3,4], since the real signals (speech, biomedical) are limited in amplitude. The present paper aims to extend this method to a type of nonlinear mixture that approximately models the non linearities introduced in sensors. We believe, in agreement with other authors [5], that an adequate mixture model is the post-nonlinear (PNL) model. Thus, (1) may be expressed

متن کاملStochastic Approximation and a Nonlocally Weighted Soft-constrained Recursive Algorithm for Blind Separation of Reverberant Speech Mixtures
We review statistical equations for blind source separation problems, then introduce their stochastic approximation and recursive algorithms. The recurrence resembles discretization of nonlinear systems of ordinary differential equations which may not have global solutions in general. Though scaling variables were used before to control finite time blowup, instabilities may arise from small div...
متن کاملA Natural Gradient Convolutive Blind Source Separation Algorithm for Speech Mixtures
In this paper, a novel algorithm for separating mixtures of multiple speech signals measured by multiple microphones in a room environment is proposed. The algorithm is a modification of an existing approach for density-based multichannel blind deconvolution using natural gradient adaptation. It employs linear predictors within the coefficient updates and produces separated speech signals whose...

In this paper we present an on line adaptive scheme for blind separation of speech signals from their convolutive mixtures This prob lem is often referred as cocktail party problem When multiple speakers speak simultaneously in tele conferencing studio we need to separate out each speaker from their mixtures If mix tures are assumed as instantaneous mixtures then it becomes standard blind sourc...
متن کاملBlind Separation of L Sources from M Mixtures of Speech Signals
In many real-world applications of blind source separation, the number of mixture signals, M available for analysis often differs from the number of sources, L which may be present. In this paper, we extend a successful and efficient kurtosis maximization algorithm used in speech separation of two sources from two linear mixtures for use in problems with arbitrary numbers of sources and mixture...
