Abstract
A microphone array for speech pick-up is presented. This array, intended to be used in multimedia workstations for hands-free communication, is based on simple acoustic principles and it has been implemented with standard technology. Performance characteristics are given in terms of acoustic behaviour; moreover, results of a listening test are presented which show that speech picked up by the array is systematically preferred to speech picked up by a standard unidirectional microphone
