Abstract

A system has been developed that enables a wanted speech signal to be extracted from a background of unwanted speech and other interference under real-life conditions. Using only two microphones 25 cm apart it exploits directional and harmonicity cues in a hybrid algorithm which takes advantages ofboth. The output of the algorithm has been tested subjectively by human listeners, and objectively by a speech recognition system. These tests show improved intelligibility of the wanted speech signal. In one set of tests, for example, the performance of a speech recogniser after segregation was similar at a signal to noise ratio of 6 dB as without segregation at a signalto noise ratio of 20 dB.
