It's astonishing to me how people hear things differently.

Honestly to my ears it sounds like a feminine voice (at least making a stab at) speaking in an American accent.

Why would Lawson deliberately do that for one line?

We know that for ROTJ they dubbed an actress with a male voice, it's possible that Lawson wasn't available to re-do that one line.

Seeing as it's a minority thing it's probably time to drop the topic here but I thought I'd bring it up as it may have been of interest.

While I never thought it was Leia, I did always notice how that line doesn't sound right. It is softly spoken and a bit effeminate, and I never liked it. No idea why it's like that, though. *shrugs*

By the way, an actress in Jedi dubbed by a man? I'm very tired as I write this, so am I forgetting something really obvious?
