“…With the progress of Artificial Intelligence (AI), as well as NLP (Natural Language Processing), which is clearly seen in modern conversational {systems [6,7], the man-machine collaboration becomes an urgent and promising trend in modern industry. Nevertheless, despite recent significant advancements [8][9][10][11] in the field of Human-Computer Interaction (HCI) (namely: the Amazon Echo available since 2015 [12][13][14], Microsoft Cortana massively expanding in 2015 to numerous platforms [15], Google Speech announced in 2016, upgraded in 2018 [16] and 2022 [17], Google Assistant announced in 2016 [18,19], Google Nest introduced as Google Home also in 2016 [20][21][22][23][24], and the Apple Siri updated in 2017 [25,26]) and undoubtful progress in Artificial Intelligence and Machine Learning [27][28][29][30], conversational AI systems usually still tend to disappoint rather than to amaze their interlocutors (and there are some specific reasons for that, already diagnosed and described [31]). In the case of industrial solutions, an appropriate sensor network with insight into every aspect of the man-machine communication with regard to its purpose is required (allowing later to provide insight into the quality and efficiency of every stage of the process for a given worker/trainee).…”
