The typing only thing is a bit unfortunate. There are enough voice modulators out there that they could probably pay for. V-tubers do it all the time. I don't really care about the voice, just that they can speak the language properly.

What would be great for interviews in pair programming and working on a solution to some realistic thing e.g take an opensource repo that solved a problem and work together with the person to try and resolve it. You could also put them in mock situations where they have to resolve a disagreement about something e.g how something should be documented, or reason about why a subpar solution has to stay in place, etc.

Just do something that would actually happen at work instead of these "how would you implement a linked list" or "implement a b-tree" or "please take this personality test before we can have a technical interview"...
