In this paper, we propose a new optimization scheme of the strength of spectral subtraction
based on musical noise assessment via higherorder statistics. Spectral subtraction often …

This paper focuses on two representative single-microphone noise reduction problems:
speech distortion and musical noise. Many noise reduction methods have been proposed …

In this paper, we propose a two-microphone noise reduction method to deal with non-
stationary interfering noises in multiple-noise-source environments in which the traditional …

This paper presents a new frequency domain blind signal extraction (FD-BSE) method for
the extraction of a target speech in presence of diffuse background noise. This is a fast …

In this paper, we proposed a new blind speech extraction method consisting of Wiener
filtering and noise estimation based on independent component analysis (ICA). First, we …

The speech enhancement architecture presented in this paper is specifically developed for
hands-free robot spoken dialog systems. It is designed to take advantage of additional …

Many noise reduction techniques generate two frequently occurring problems: speech
distortion and musical noise. A number of methods have been proposed to solve these …

In this paper, we conduct an analysis for reduction of musical noise in integration method of
microphone array signal processing and nonlinear signal processing. In these days, for …

The model of the human/machine hands-free speech interface is defined as a point source
(the user voice) and a diffuse background noise. This situation is very different from the …

In this paper, we construct a hands-free robot spoken dialogue system based on the real-
time blind spatial subtraction array (BSSA) and evaluate the system. BSSA is the blind …
