  • In this American English pronunciation

  • video, were going to learn how to

  • pronounce the AA as in BAT vowel.

  • This is a sound that changes depending

  • on the following sound. So, it can either

  • be a pure vowel or a modified vowel.

  • Well go over both in this video.

  • To make the pure AA vowel, the jaw

  • drops quite a bit, AA.

  • The tip of the tongue stays forward; it’s

  • touching the back of the bottom front

  • teeth, AA. The back part of the tongue

  • stretches up.

  • The tongue is wide, AA. Because the

  • tongue is high in the back and low in

  • the front, you can see a lot of it. This is

  • different from the 'ah' as in 'father'

  • vowel, for example, where the tongue

  • presses down in the back and you see

  • more dark space in the mouth. AA, AH.

  • You can also see the corners of the

  • mouth pull back and up a little bit. AA.

  • Let’s take a look at the pure AA vowel

  • up close and in slow motion.

  • The tongue tip is down and the back of

  • the tongue lifts. Here’s the wordsat’.

  • The tongue position is easy to see

  • because of the jaw drop needed for this

  • vowel.

  • When AA is in a stressed syllable, the

  • vowel will go up and come down in

  • pitch, AA. Sat, AA. In an unstressed

  • syllable, the vowel is flatter and lower

  • in pitch, quieter, aa. This vowel is

  • unstressed in the second syllable of

  • backtrack’. Let’s look up close and

  • in slow motion.

  • In the first, stressed syllable, the jaw

  • drops, and we see the corners of the

  • lips pull back and up for the stressed

  • AA. In the unstressed syllable, the jaw

  • drops less. Let’s compare them.

  • On top is the stressed AA. You can see

  • the jaw drops more. For the unstressed

  • AA, the corners of the lips are a little

  • more relaxed than in the stressed

  • version, where they pull slightly back

  • and up.

  • Generally, the unstressed version of a

  • vowel or diphthong is more relaxed and

  • doesn’t take the full mouth position, in

  • this case, a little less jaw drop, and

  • relaxed lips. This is because unstressed

  • syllables are shorter, so we don’t take

  • the time to make the full position.

  • At the beginning of this video, I said the

  • AA vowel is not always a pure AA. This

  • vowel changes when it’s followed by a

  • nasal consonant. When it’s followed by

  • the M or N sounds, the tongue relaxes

  • in the back, making an UH sound after

  • AA. AA-UH. It’s not a pure AA sound.

  • Unfortunately, this change is not

  • represented in the International

  • Phonetic Alphabet. It’s still written with

  • the same AA symbol. So, you just have

  • to know when it’s followed by [m] or

  • [n], it’s different.

  • We don’t sayman’, aa, ‘man’, with a

  • pure AA. We sayman’, aa-uh, aa-uh,

  • relaxing the tongue and corners of the

  • lips before the consonant. You can

  • think of this UH relaxation as theuhas

  • inbuttersound or schwa sound. Let’s

  • look up close and in slow motion at the

  • wordexam’.

  • First we see the familiar shape of the

  • mouth, when the AA is in a stressed

  • syllable. Watch how the relaxation

  • happens: the corners of the lips relax

  • in. The tongue will relax down in the

  • back. And the lips close for the M

  • consonant.

  • This relaxation of the corner of the lips

  • and back of the tongue happens when

  • the AA vowel is followed by the N

  • consonant as well. For example, the

  • wordhand’. Haa-uhnd. Hand.

  • So, when you see this symbol followed

  • by this symbol or this symbol, it’s no

  • longer a pure AA. Think of relaxing out

  • of the vowel, AA-UH.

  • If the next sound is the NG consonant,

  • it’s a little different. Rather thanaa-

  • uh’, the vowel changes into AY. It’s

  • really like the AY as in SAY diphthong.

  • First, the middle part of the tongue lifts

  • towards the roof of the mouth, then the

  • front part of the tongue. Let’s watch

  • gangup close and in slow motion.

  • The position for the first sound looks a

  • lot like AA, but the part of the tongue

  • lifting up is more forward. Gaaaang.

  • Then the front part of the tongue

  • arches up towards the roof of the

  • mouth, while the tongue tip remains

  • down.

  • When you see this symbol followed by

  • this symbol, it’s no longer a pure AA.

  • It’s more like AY. Gang. Thanks.

  • Pure stressed AA: Sat, aa

  • Pure unstressed AA: backtrack, aa

  • AA, aa, AA, aa.

  • AA vowel modified by M: exam, aa-uh

  • AA vowel modified by N: man, aa-uh

  • AA vowel modified by NG: gang, ay

  • Example words. Repeat with me:

  • Chapter, can, act, last, bank, bypass.
