Abstract
Enhancing speech from audio signals recorded using several microphones is of interest to many audio applications such as human-computer interfaces and teleconference systems. With an increasing availability of low-cost micro-electro-mechanical systems (MEMS) and powerful processing units, embedded systems are capable of recording and processing several audio signals in realtime. In this paper, an overview of the entire signal processing chain from audio signal acquisition with an array of MEMS microphones to the signal enhancement using directional filtering is provided. The presented results indicate that good noise and interference suppression can be achieved in realtime using an embedded system equipped with low-cost microphones.
