Syllables and stress
Split it into 3 beats. The highlighted syllable is the strong one: say it louder, longer and a touch higher in pitch, and let the others fall away. English is a stress-timed language, so getting ɑː in the right place matters more to a listener than getting every vowel perfect.
Stress pattern Ooō — capital letters mark the stressed beats.
