Americans pronounce tournaments as TOR-nuh-muhnts (/ˈtɔrnəmənts/). In "tournaments", 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, and it's why Americans sound more relaxed than the textbook. It comes out as TOR·nuh·muhnts. Stress falls on the first syllable — keep everything else short and quick. You'll hear it in sentences like "She competes in fencing tournaments around the country" or "I learned to play chess and now compete in local tournaments" — more examples below.
