Pronunciation = how a word is said/spoken.
Accent = the specific characteristics of a person's voice, based on region, nationality etc; a mark on a letter (see below)
You said "If I accentuate(write verb?) the works wrongly..."
First, I think you meant "words", not "works".
Second, "to accentuate" means to intensify or to emphasise. However, it does also mean "to mark with an accent", but we don't use accents in written English. We stress specific syllables but they are not marked in the written words. The only "marks" that are used in written English are punctuation marks.
