Abstract

This paper presents a prototype system for Blind Source Separation (BSS) of many speech signals and describes the techniques used in the system. Our system uses 8 microphones located at the vertexes of a 4cm × 4cm × 4cm cube and has the ability to separate signals distributed in three-dimensional space. The mixed signals observed by the microphone array are processed by Independent Component Analysis (ICA) in the frequency domain and separated into a given number of signals (up to 8). We carried out experiments in an ordinary office and obtained more than 20 dB of SIR improvement.
