te-tsu-da-u, four beats, with a proper affricate in second place and a bare vowel at the end.
tetsudau
The crest sits on da; all four units are the same length. The word combines both of Japanese's classic English-speaker traps in one place — an affricate that gets split and a final vowel that gets absorbed — so producing four honest beats requires attention at both ends.

ちょっと手伝ってくれませんか opens with ちょっと, four morae including a geminate silent beat, and then 手伝って adds another geminate: te-tsu-da-t-te, five morae. Two held silences in one short request is a lot of pure time, and rushing either of them is what makes a beginner's Japanese sound clipped.
"tet-soo-DOW" gathers every error: the affricate split across a boundary, a rounded u, a stressed third beat, and the final two morae fused into an English diphthong. Keep the tsu whole and flat-lipped, level the emphasis, and pulse the closing a and u apart until four beats are automatic.
