Introduction

Abstract

In our daily lives, speech communication devices are omnipresent and have gained much interest in recent years. Widely available consumer products like smartphones, laptops, tablets or the most recently introduced smart loudspeakers are equipped with acoustic sensors that allow to perform a wide range of tasks in terms of speech signal capturing. For example, these include conversations with far end speakers, teleconferencing applications with multiple participants or the use of voice recognition software for speech to text applications, voice control for navigation systems or the utilization of world wide web services.
