Some people taste words

Live Science says some people “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.” They say that “phonograph” tastes of Dutch chocolate. “[M]any of the synesthetes reported words with the sounds “eh” or “mmm” tasted of mint, and that those containing the sound “aye” tended to taste of bacon.”

I don’t do this, but I think it would make reading a novel much more interesting. I wonder if they taste words all the time.
