Plane_arium
In one South Park episode the owner of a planetarium has a single-word speech impediment. He can't pronounce the
t in plane
tarium, but he can pronounce other
t sounds.
A funny premise, but it's not entirely fictional.
(1) There's a public service announcement discouraging software copying, in which the announcer says "softwurr" every time. The rest of his speech is normal.
(2) A radio spot for some kind of gasoline additive in which the announcer says "gazoline" every time, but pronounces
s normally in other words.
I'm wondering if these are deliberate errors, subliminal ways to pin your attention to the important word...?
