I haven't tested this extensively but run a transcript on a zoom meeting with between 2 people with Australian accent and one with American accent and it quickly transcribed almost flawlessly.

In the transcript and shows speaker 1, speaker 2, speaker 3 etc, however struggles to attribute the correct dialogue to the correct speaker.

Eg,
Speaker 1 Hey, Nick, how

Speaker 2 are you? Good, John.

Speaker 3 How are

Speaker 1 you? Yeah, very well. Thanks. Cindy will be here in just a moment.

Overall it's not a big deal, and might be improved, but first impressions for the price are pretty good.
