In this American English pronunciation
video, we’re 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.
We’ll 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 word ‘sat’.
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 say ‘man’, aa, ‘man’, with a
pure AA. We say ‘man’, aa-uh, aa-uh,
relaxing the tongue and corners of the
lips before the consonant. You can
think of this UH relaxation as the ‘uh’ as
in ‘butter’ sound or schwa sound. Let’s
look up close and in slow motion at the
word ‘exam’.
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
word ‘hand’. 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 than ‘aa-
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
‘gang’ up 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

在这个美式英语发音
视频中,我们将学习如何
像 BAT 元音一样发音 AA。
这是根据以下声音而变化
的声音。 因此,它既
可以是纯元音,也可以是修饰元音。
我们将在这段视频中讨论这两个问题。
为了发出纯AA元音,下巴
下降了很多,AA。
舌尖向前; 它正在
接触下门牙的后部
,AA。 舌头的后部
向上伸展。
舌头很宽,AA。 因为
舌头后高前低
,所以可以看到很多。 这
与“父亲”元音中的“啊”不同
,例如,舌头
在后面向下压,你会看到
嘴里有更多的黑暗空间。 啊,啊。
您还可以看到
嘴角向后和向上拉一点。 AA。
让我们近距离和慢动作看一下纯 AA 元音
。
舌尖向下,
舌后部抬起。 这里是“坐”这个词。 由于
这个元音需要下颚下垂,所以很容易看到舌头的位置
。
当 AA 在重读音节中时,
元音会在音高上上升和下降
,AA。 星期六,AA。 在非
重读音节中,元音更平,
音调更低,更安静,aa。 这个
元音在“backtrack”的第二个音节中没有重读
。 让我们近距离观察
慢动作。
在第一个重读音节中,下巴
下垂,我们看到
唇角为重读 AA 向后拉
。 在非重读音节中,下巴
下垂较少。 让我们比较一下。
最上面是强调的AA。 你可以
看到下巴掉得更多。 对于无压力的
AA,嘴唇的角
比有压力的版本稍微放松一点
,它们会稍微向后
和向上拉。
一般来说,
元音或双元音的非重读版本更放松,
不会占据全嘴位置,在
这种情况下,下巴下垂少一点,
嘴唇放松。 这是因为非
重读音节较短,所以我们不会
花时间来做完整的位置。
在这个视频的开头,我说过
AA 元音并不总是纯 AA。
当后面跟着一个鼻辅音时,这个元音会发生变化
。 当它后面
跟着 M 或 N 音时,舌头
在后面放松,在 AA 之后发出 UH 音
。 AA-呃。 这不是纯粹的 AA 声音。
不幸的是,这种变化
在
国际音标中没有体现。 它仍然
用相同的 AA 符号书写。 所以,你只
需要知道它什么时候跟着 [m] 或
[n],它是不同的。
我们不会用纯 AA 说“人”、“人”、“人”
。 我们说“男人”,aa-uh,aa-uh,
在辅音前放松舌头和唇角。 您可以
将这种 UH 放松视为“uh”,
如“butter”声音或 schwa 声音。 让我们
仔细看看
“考试”这个词。
首先,我们看到熟悉的
嘴巴形状,AA 位于重读
音节中。 观察放松是如何
发生的:唇角
放松。舌头在
后面放松。 M
辅音时嘴唇闭合。
当 AA 元音后面跟着 N
辅音时,唇角和舌后部就会放松。 例如,
“手”这个词。 哈-嗯。 手。
因此,当您看到此符号
后跟此符号或此符号时,它
不再是纯 AA。 想想
放松元音AA-UH。
如果下一个声音是 NG 辅音,
那就有点不同了。 元音不是“a-
uh”,而是变为 AY。 它
真的很像 SAY 双元音中的 AY。
首先,舌头的中部
向口腔顶部抬起,然后
是舌头的前部。 让我们
近距离和慢动作观看“帮派”。
第一个声音的位置看起来
很像AA,但舌头
上扬的部分更靠前。 高昂。
然后舌头的前部
向上拱向嘴巴的顶部
,而舌尖保持
向下。
当您看到此符号后跟
此符号时,它不再是纯 AA。
更像是AY。 刚。 谢谢。
纯重音 AA:Sat,aa
纯无重音 AA:回溯,aa
AA,aa,AA,aa。
AA 元音 M 修饰:exam,aa-uh
AA 元音 N 修饰:man,aa-uh
AA 元音 NG 修饰:gang,ay
例句。 跟我重复一遍:
