VUI Interfaces – it is learning, personalized AI?

Good day,

In reference to recent experience and check for possible affordances in scope of Voice interfaces in practise, several questions appeared that may define the quality of the service provided (Siri, Google Assistant)

What is the level of sophistication of the algorithms in the context of user experience?

  • Do assistants have personality traits?
  • Do they learn from every interaction?
  • Can they modulate the voice?
  • Can they have moods?
  • Depending on the owner and the situation, can the degree of formalization of the relation change?
