Japanese · Pronunciation Guide
tsu-ka-u, three beats, opening with a true affricate and ending on a bare vowel of its own.
tsukau
Tap three times and the word fits, with no accent to break the flatness. The word contains both of the things English speakers most reliably mis-time: an affricate that gets split into two, and a final vowel that gets absorbed into the one before it. Getting three honest beats out of it is genuinely an achievement.

このペンを使ってもいいですか shows the te-form 使って, where the tsu turns into a geminate — tsu-ka-t-te, with a silent held beat before the t releases. So within one sentence the same verb demonstrates an affricate and a doubled consonant, the two different jobs the small っ and the つ kana can do.
"tsoo-KAH-oo" or, more commonly, "soo-KOW" — the t dropped from the affricate and the final two vowels crushed into an English diphthong. Both need fixing: keep the t audible inside a single tsu gesture, keep the lips flat, and give the closing u its own beat instead of letting it become the tail of "kow."
