I used to, then I grew up. However, what I’ve found is that being able to do accents can occasionally help communicate a word. If you’re talking to someone that has a different accent and you just can’t get them to understand some particular word, pronouncing it how you think they’d pronounce it might help. It changes how certain letters and combinations are pronounced, helping the other person visualize the letters and therefore the word.

There’s times between English and Spanish where the spelling is functionally the same, but pronunciation is incredibly foreign in the other language. Words ending in -tion are “shin” in english but -cion is “see own” in Spanish. Many such words have latin roots, so the base word is similar like “communication” on “construction”.

But, first and foremost, enunciate clearly. Speaking slower doesn’t help if you’re still dragging your consonants the same way.
