Americans pronounce participants as par-TIH-suh-puhnts (/pɑrˈtɪsəpənts/). In "participants", 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 par·TIH·suh·puhnts. Stress falls on the second syllable — keep everything else short and quick. You'll hear it in sentences like "The boot camp class pushes participants to their limits" or "The ethics committee approved the study involving human participants" — more examples below.

The textbook way isn't wrong — it's just not how anyone actually says it.
In "participants", 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. /t/ is dropped entirely — the surrounding consonants flow together without the T.
In "participants", the short unstressed vowel before "n" disappears — the schwa is absorbed and the "n" becomes the syllable nucleus on its own. Schwa is absorbed — consonant becomes the syllable nucleus.
Stress falls on the second syllable, not the others. Stretch TIH — keep everything else short and quick.
Don't pronounce the second syllable too fully. The unstressed syllable reduces to a schwa — the lazy "uh" sound — in casual speech.
