Raise the back of your tongue to touch the soft palate (velum). Stop the air, then release.

Americans pronounce considered as kuhn-SIH-derd (/kənˈsɪdərd/). In "considered", 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 kuhn·SIH·tert, you get kuhn·SIH·derd. Stress falls on the second syllable — keep everything else short and quick. You'll hear it in sentences like "Access to education is considered a basic right for all children" or "Censorship of the press is considered a violation of free speech" — more examples below.
Record yourself saying "considered" and play it back. The mic stays on your device — nothing's uploaded.

The textbook way isn't wrong — it's just not how anyone actually says it.
In "considered", 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.
In "considered", 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.
Stress falls on the second syllable, not the others. Stretch SIH — keep everything else short and quick.
Don't pronounce the first syllable too fully. The unstressed syllable reduces to a schwa — the lazy "uh" sound — in casual speech.
