there are three sounds in American
English what is the difference between
these three sounds let's start with the
UH as in butter ah as you can see there
is some drop in the jaw ah and the
tongue is resting on the bottom of the
mouth touching just behind these teeth
ah ah the schwa is similar the tongue
position is the same resting on the
bottom of the mouth touching just there
however there is not the drop in the jaw
uh uh uh the UH as in pull this has some
drop of the job with the lips do
something completely different they come
out a little bit because they person
here at the corners pull now there are
how-to videos for each of these three
sounds but I wanted to bring them
together so that we could compare let's
look at some photos all of the photos
were taken as I said the word that
contains the sound not just the sound by
itself here you see the as the butter
and as in supply sounds compared on the
left the UH as in butter you can see
that the jaw is dropping more the teeth
are further apart and the chin is
further down here is butter versus pull
you can see the corners of the mouth in
pull are coming together just a little
bit
this brings the top and bottom lip away
from the face the top lip here is
covering the front teeth whereas with
the UH as in butter sound you can see
just a bit of the top teeth here are all
three again you can see that the jaw is
dropped more on butter leaving more
space between the top and bottom lips
here are butter and pull and profile it
is difficult to see but the corners of
the mouth in pull have come in a little
bit and the mouth looks slightly less
relaxed you can see a change in the top
lip as it has slightly pulled away from
the face here are all three in profile
now let's look at a few sample words
first the schwa or as in supply sound
supply sofa condition condition has two
choise in the first and the last
syllable condition conduct compose the
UH as in pull sound pull good should
could the UH as in butter butter
mother brother because and because it is
the second syllable because one last
note the schwa sound only occurs in
unaccented syllables this means that the
length will most likely be shorter than
the other two vowel sounds when they
occur in accented syllables

美式英语中有三个音
这三个音有什么区别 让我们从 UH 开始，
就像黄油一样
这些牙齿
啊啊施瓦是相似的，舌头的
位置是一样的，靠在
嘴巴的底部，只是在那里接触，
但是下巴没有下降，
呃呃呃呃呃，就像拉扯一样，这有一些
下降的工作 嘴唇做了
一些完全不同的事情，
它们有点突出，因为
他们在角落里拉扯现在有
这三种声音中每一种的操作视频，
但我想把它们
放在一起，这样我们就可以比较让我们
看一些照片
照片是在我说这个词时拍摄的
牙齿
之间的距离越远，下巴
越往下，这是黄油与拉力的对比，
你可以看到拉力中的嘴角
会聚在一起一点点，
这会使上唇和下唇
远离脸部 这里的上唇
覆盖前牙，
而在黄油声音中，你可以看到
上面的牙齿只有一点，这里都是
三个，你可以看到下巴
更多地落在黄油
上，在上下嘴唇之间留下更多空间
黄油和拉力和轮廓
很难看到，但是
拉力中的嘴角已经有点进来了
，嘴巴看起来稍微不那么
放松了你可以看到上唇的变化，
因为它稍微远离
了脸部 三个都是轮廓
现在让我们先看几个示例
词 schwa 或 as in 供应声音
供应沙发条件条件
在第一个和最后一个
音节有两个选择条件进行组成
UH as in pull sound pull good
UH 应该可以像黄油黄油
妈妈兄弟那样，因为它
是第二个音节，因为最后一个
音符 schwa 声音只出现在
非重音音节中，这意味着当它们出现时，
长度很可能
比其他两个元音短
重读音节
