but ㅅ has a softer 's' pronounciation whereas ㅆ has a more excentuated SS sound where you move air with the bottom and top of your teeth put together when spoken
for the actual words themselves 살 is like the fat/skin of something and 쌀 is rice, def don't want to mix up the two🤗
ITT: people not knowing the difference between allophone and homophone.
I don't think that it's the case here. It's simply that OP's meme leaves a lot of stuff up to context, and people are filling the gaps with assumptions. We [people in general] shouldn't assume ignorance out of simple miscommunication.
In case someone here does not know the difference:
Allophones - sounds associated with the same phoneme in a certain language. For example, in English [pʰ] (as in "pit") and [p] (as in "spit") are allophones, as they convey the same phoneme /p/.
Homophones - different words that sound the same. For example, in English "two" and "too" are homophones for most speakers, as they're typically pronounced [tʰu̟ː] and parsed as /tuː/.
살 /sal/ "meat" is pronounced with [sʰ]. It's roughly like the "ssh" in "grasshopper".
쌀 /s͈al/ "uncooked rice" uses [s͈] instead. It's a "tense" consonant; if I got it right the main difference is faucalised voice, you're supposed to lower the larynx a bit while speaking it.
Since the difference yields different words, they're a minimal pair so they aren't allophones but different phonemes. If you speak Korean (I don't) the difference between those two is on the same level as the one between English "bot" vs. "pot", or between "bit" and "beet". However since the contrast isn't common out there they sound similar for non-speakers, and I think this to be what OP is trying to convey.
Oh it's so hard sometimes to get these differences because one just... doesn't get it. Doesn't have experience of the difference.
In Finnish vowel length matters a lot, and when there are non-native speakers, it's painfully obvious, as that's something that's hard to "get right" if you haven't been exposed to the difference since you were a kid.
It's probably a somewhat subjective feeling of mine, but I'm pretty sure it's easier to pass as a native speaker of English to English native speakers than it would be to do the same for Finnish. Similarly I'd have a lot of trouble learning the tonal and other minor differences in lots of Asian languages as Finnish or English or any other language I speak doesn't really utilise them as much. So I'm "deaf" to them. For now.
