Where is "Welcome to Baldur's Gate" said?

[Enjay]

Bit of an odd one: years ago, when I played the original Baldur's Gate, my friends and I got obsessed with the sound that we heard so often: someone saying in an overly enthusiastic way "Welcome to Baldur's Gate."

We weren't the only ones. It's a thing. Pretty much every website that has anything to do with Baldur's Gate opens with text saying "Welcome to Baldur's Gate."

But here's the thing - I can't find the sound anywhere. My daughter has played through the enhanced edition recently and was disappointed not to hear the "Welcome to Baldur's Gate" line that her dad would still quote far too often.

We have extracted the sound files and listened to as many as sanity will allow.
We've watched videos.
We saw the non-interactive pre-release video, and someone does say the line - but it's not said in the way I remember.

Running out of ideas. So, I come to the good people of this forum for help.

Can anyone verify that this is even a thing and not some weird Mandela effect? Even better, provide a link to the sound (or tell us the name of the sound file from the game)?

Thank you kindly.
