I struggle to have naturally flowing conversation with an AI for much the same reason people don't use most of Siri's features - it's awkward and feels strange.

As such I can maintain about five minutes of slow pace before giving up and typing. I have to believe others have similar experiences. But perhaps I'm an outlier.

I feel tiredness in my throat when I talk to bots like Alexa as you have to enunciate in a special way to get across to them.

Sure, it defiantly doesn’t work for everyone. I think it’s accent or something dependent as some people’s natural voice comes across fine.
