I will admit watching the ANH clip posted above does sound a little different than I remember. Not drastically so. It’s obviously the same recording. Just… a little more processed? Or processed a little differently? Something.
In 2004 they tried to match his voice to the sequels. I’m surprised if people hadn’t noticed, I’ve only seen the 2004 version 3 times and noticed straight away!
Edit: and I didn’t even click the links so I don’t know what’s in them.
