How to pronounce accumulated in American English
Americans pronounce accumulated as uh-KYOO-myuh-lay-tuhd (/əˈkjumjəˌleɪɾəd/). In "accumulated", the "t" between vowels sounds like a quick "d" — the tongue briefly taps the ridge behind the upper teeth. This is called the Flap T, a hallmark of natural-sounding American speech. So instead of uh·KYOO·myuh·lay·tuht, you get uh·KYOO·myuh·LAY·tuhd. Stress falls on the second syllable — keep everything else short and quick. You'll hear it in sentences like "She accumulated too many fouls and fouled out of the game".

The lips stay neutral or pre-shape for the upcoming vowel (rounding early for OO in <em>youth</em>, for example).

The textbook way isn't wrong — it's just not how anyone actually says it.
Saying a hard "T" in the middle.
In "accumulated", the "t" between vowels sounds like a quick "d" — the tongue briefly taps the ridge behind the upper teeth. /t/ or /d/ becomes a quick tap [ɾ] — sounds like a soft D. The tongue briefly taps the ridge behind the upper teeth.
Releasing the final consonant with a puff of air.
In "accumulated", the "d" is not released — the articulators get into position but hold without the burst of air. Air stops but there's no release burst — the articulators hold position.
Stressing the wrong syllable.
Stress falls on the second syllable, not the others. Stretch KYOO — keep everything else short and quick.
Pronouncing the first syllable too fully.
Don't pronounce the first syllable too fully. The unstressed syllable reduces to a schwa — the lazy "uh" sound — in casual speech.
