This article presents a problem of improvement of speech signals for their direct use to the voice control in automation and robotics, i.e. for the realization of the so-called human-machine interfaces (HMI's). It is shown that significant improvement of the speech intelligibility, and thus, performance of the automatic speech recognition (ASR) systems, can be achieved by application of a microphone array and an appropriate algorithm for directional filtering. An experimental hardware (and software) has been worked out using the TMS320C6711 digital signal processor (DSP) by Texas Instruments Inc.
