Done The dots next to the characters in a speech bubble...?

[Amzy]

What are those dots next to the characters for? Do they just indicate emphasis? If someone would kindly explain this to me, I'd much appreciate it.

Yes, they're just emphasis. I usually use italics for them.

Thanks! I always just assumed they were, but I wanted to confirm.
