Boat Isn't Just One Shape: English Vowels Glide

Greek vowels tend to stay level and steady for their entire length, so it's natural to treat every English vowel the same way. But several common English vowels are actually glides: the vowel in 'day' starts in one mouth position and slides toward another by the end, and so does the vowel in 'boat' or 'go.' If you keep these vowels flat and steady, words like 'day' or 'go' can sound clipped to American ears, even though every individual sound is technically correct. Try saying 'day' slowly, feeling your tongue rise and your lips tighten slightly near the end — that movement is part of the sound itself, not optional decoration. Do the same with 'go,' feeling your lips round further by the finish. For two minutes today, stretch out 'day, go, say, show' in slow motion, exaggerating the glide at the end of each one. Once you feel that shift, your vowels will sound noticeably more natural.
