The paper describes a 2D sound source mapping system for a mobile robot. We developed
a multiple sound sources localization method for a mobile robot with a 32 channel …

Unknown global permutation of the separated sources, time-varying source activity and
under determination are common problems affecting on-line Independent Vector Analysis …

This paper deals with the problem of the underdetermined blind separation and tracking of
moving sources. In practical situations, sound sources such as human speakers can move …

Independent Vector Analysis is a powerful tool for estimating the broadband acoustic
transfer function between multiple sources and the microphones in the frequency domain. In …

Blind separation of convolutive mixtures is a very complicated task that has applications in
many fields of speech and audio processing, such as hearing aids and man-machine …

This paper presents a new method for underdetermined Blind Source Separation (BSS),
based on a concept called multichannel complex non-negative matrix factorization (NMF) …

This paper deals with the problem of underdetermined blind source separation (BSS) where
the number of sources is unknown. We propose a BSS approach that simultaneously …

This paper describes a speech recognition system that detects basic voice commands for a
mobile robot operating in a home space. The system recognizes arbitrary timed speech with …

A sound processing apparatus includes a sound determination portion operable to
determine whether an input sound includes a first sound emitted from a particular source …
