It could b synaesthesia, if I listen to music I can see shapes explain a texture and sometimes a taste so I'd say they're the same thing, theres many ways for it to work
Here's a definition of tasting words (A very small number of synesthetes can "taste" words. A new study finds that individuals with this last form of synesthesia—called "lexical-gustatory" synesthesia—can taste a word before they ever speak it, and that the word's meaning, not its sound or spelling, is what triggers this taste sensation.)
This manga suddenly reminded of someone I came across who can actually taste words. His favorite words is earthquake which tatse like chocolate.
