Americans pronounce consideration as kuhn-sih-der-AY-shuhn (/kənˌsɪdəˈreɪʃən/). In "consideration", 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, and it's why Americans sound more relaxed than the textbook. So instead of kuhn·sih·ter·AY·shuhn, you get kuhn·SIH·der·AY·shuhn. Stress falls on the fourth syllable — keep everything else short and quick. You'll hear it in sentences like "That is a fair point, and I will take it into consideration" or "I would like to propose a counteroffer for your consideration" — more examples below.
