This sounds like something only Elon Musk would be concerned. In Judaism, we are obligated to rely on our senses, not magic or false prophets. It is with the help of our faculty and abilities that we should determine that the voice in question (in any given conversation) is simply an act of AI, and not a divine agency. This is because the brain perceives information which is transferred to the eyes and shifted into vision, in relation to light and a physical object. That is to say, information entering the brain is interpreted as color, texture, size, etc. We are, in essence, a mechanical machine. Consider an advanced computer system with all its wires which would employ a binary code, which is measurable in fixed numerical quantities, operating in a range of complex system. This is how the human body was designed. So in the near future, it is possible that virtual reality could mingle both realities to the point of incomprehensibility. Our reliability to reality would be variable, liable to change to any pattern of events as in the movie matrix. Which begs the question. How can we be sure that we are not deceived or fooled into believing anything?
In his Guide, the Rambam gives a clear answer to this rule. Since G-d does not involve Himself in human affairs, that is, G-d established the laws of nature at the beginning and does not need a step into history, it follows that G-d never spoke to anyone. And since the angels are a force of nature, not divine (agentic creatures with wings and blond hair), but the will of a deity, we can be sure that the voice stemming is a computer-generated replica of the human vocal cords. Rest assured, in this pretext, the voice does not come from G-d, because G-d does not have a mouth to speak to prophets or to man. Refer to Maimonides' view on prophecy.
