Natural user interfaces and new languages

Human-computer interfaces are changing the way real-world experiences take place.
When we want to establish an interaction between man and machine, we see cognitive questions taking place on both sides: machine and man. On the one hand the machine is required to understand on the basis of what previously learned (machine learning), on the other hand man is required to limit and simplify the language and interactions using voice commands, tactile and gestural without any interpretative variant. Smart speakers, which have now became very popular, or other ASR (Automatic Speech Recognition) are based on grammar, lexical terms and acoustic recognition modules, these systems have taught us to express ourselves in a simplified way.
The success of these ASR tools is due to the fact that users can interact directly with the computer without using an intermediate device (eg, mouse, keyboard), without particular technological expertise, actually reducing the grammatical structure of language and lexical quality to the absolute essentials.
