A binaural hearing-aid system based on two-stage blind sound source separation (BSS) method is now being studied by some of the authors. This system consists of two techniques; a single-input multiple-output (SIMO)-model-based independent component analysis part and binaural-output-capable SIMO-model-based binary masking (SIMO-BM) parts. However owing to user-specific head-related transfer function...
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 usual cocktail party model, separation of a mixture of speeches, that is usually treated in frequency domain blind signal separation (FD-BSS). In particular, the fast permutation solvers proposed for the cocktail party model...
Blind separation of binaural mixed sounds using single-input multiple-output (SIMO)-model-based independent component analysis (SIMO-ICA) with self-generator for initial filter (SIMO-ICA-SG) is now being studied by the authors. This method contains frequency-domain ICA (FDICA-PB), single-talk detection, direction of arrival (DOA) estimation, head related transfer function (HRTF) matrix bank, and SIMO-ICA...
