coat vs caught: hear and say the difference
coat and caught are identical except for one sound: coat has the long o, /oʊ/, and caught has the aw vowel, /ɔː/. AW is one steady rounded vowel held to the end; long O starts lower and slides — the lips tighten during the sound, which is what makes it a glide.
