xkcd #2942: Fluid Speech
Alt text:
Thank you to linguist Gretchen McCulloch for teaching me about phonetic assimilation, and for teaching me that if you stand around in public reading texts from a linguist and murmuring example phrases to yourself, people will eventually ask if you're okay.
Nah, no need to slow down. Molasses flows faster in winter unless I'm pissed off and swearing. The t and p are distinct. The o vowels in potato get drawn out, and essentially turn into puhtaytuh, unless I'm paying attention and speaking formally but the t and p are separate. I've been annoying my wife trying to make a sentence where it happens, even asked my dad to do it so I could hear him.
I plan to annoy other family and friends tomorrow because it seems weird for something universal enough to end up in an xkcd to not happen at least enough to have encountered it, but because "hot potato" is a game, and a slang term, I've heard it a lot. I can't think of any time there wasn't at least a partial stop between the t and p, with the t being distinct. Plenty of mangling potato until it sounds like a foreign word, but that's a different thing
Maybe it's regional? Gods know the Appalachian dialect is full of some weird quirks.
You're not supposed to just say hot potato. Use it the middle of a sentence then say it fast.
Turning 'potato' into 'puhtaytuh' is an example of what they're talking about. Saying 'puhtaytuh' involves less mouth movement than saying 'potato'.
Try using 'hot potato' in a sentence and you'll probably notice that the glottal stop at the end of 'hot' gets toned down or dropped. The 't' sound will still be there, but your tounge wont move as much as if you say 'hot' on it's own.
