On the other hand, I have great difficulty following who speaks what during an online meeting. I think that most people speech arent clearly transmitted, well as a justification looking the live caption, it also contains a lot of mistake

I use live captions for this a lot and find that it's pretty accurate. It's helpful if someone says something that I don't catch and I can just scroll up the captions to make sure I understand.

Also helps if someone tries to interrupts and the live caption can notate who was the breaker so I can call on them without a dumb-sounding "uh who was that?"
