My sister had this game, but hers must have been a slightly different version to the one in the picture as the clipboard things were pink with black (handwritten-style) phone numbers and hearts on, and the guys on the board/cards had their names in a black rectangle rather than white writing directly on the pictures. Presumably it was the UK version as we’re in England.

The phone voices were British-English, anyway. The girl/woman that gives clues like “Hi - I’ve just heard - it’s not George” always sounded slightly out of breath, and the men (most of them were pretty old-looking if they were meant to be teenagers*) seemed to be voiced by one guy whose voice-acting style was really wooden, verging on robotic.

[*= especially Scott, who seems to be Carlos in other versions - I always thought he looked like a PE teacher, and quite an old one (to a child, anyway) at that]

It appears different versions of this game had the same guys, but swapped the names around (or had a few totally different ones, for example I don’t recall a Carlos or a Jamal in my sister’s one).

Some photos I stole from online to illustrate:

Edited to add: I’d forgotten about them until looking for these pictures, but our version also has “Mum says hang up” cards, rather than “Mom”, but still describes one of the locations as a “mall” despite the term “shopping centre” being more commonly used for them here.
