In this paper, we propose a new blind speech extraction method consisting of a minimum mean-square error short-time spectral amplitude (MMSE STSA) estimator and noise estimation based on independent component analysis (ICA). First, we perform a computer simulation using the artificial noise whose stationarity could be controlled parametrically, and the obtained results indicate that the proposed method...
This paper reviews a real-time two-stage blind source separation (BSS) method for convolutive mixtures of speech, in which a single-input multiple-output (SIMO)-model-based independent component analysis (ICA) and a SIMO-model-based binary masking are combined. SIMO-model-based ICA can separate the mixed signals, not into monaural source signals but into SIMO-model-based signals from independent sources...
In this paper, we propose a new spatial subtraction array (SSA) structure which includes independent component analysis (ICA)-based noise estimator. Recently, SSA has been proposed to realize noise-robust hands-free speech recognition. In SSA, noise reduction is achieved by subtracting the estimated noise power spectrum from the noisy speech power spectrum. The conventional SSA uses null beamformer...
