Bit Isn't Beat: A Vowel Vietnamese Doesn't Split

Vietnamese vowels are generally clear and don't shift quality based on tenseness the way English vowels do, so many Vietnamese speakers use the same vowel sound for both 'bit' and 'beat', relying only on length to tell them apart. In English, though, these are two completely different vowels, not just a short and long version of the same one: 'bit' uses a shorter, looser, more relaxed vowel, while 'beat' uses a tenser, higher, more spread vowel, with your lips pulled slightly wider. Mixing them up can turn 'sheep' into 'ship', or 'leave' into 'live'. Try saying 'bit' with your jaw a little more open and your tongue relaxed, then 'beat' with a tighter, higher tongue position and a small smile. Practice the pairs 'sit / seat', 'fill / feel', and 'chip / cheap', exaggerating the jaw and lip difference each time. For today's two-minute practice, record yourself saying all three pairs, then play them back and listen for whether the vowel quality really changes between each word.
