Tongue pulls back slightly from the T position, blending into R. Sounds close to 'chr'.

Americans pronounce treatments as TREET-muhnts (/ˈtritmənts/). In "treatments", the "t" is squeezed between other consonants and drops out — the surrounding consonants flow together without it — most natural in flowing, casual speech; in careful or formal speech, the T may be lightly present. This is called the Silent T in Clusters, a hallmark of natural-sounding American speech. It comes out as TREET·muhnts. Stress falls on the first syllable — keep everything else short and quick. You'll hear it in sentences like "Biotechnology advances are leading to revolutionary medical treatments".
