American English Pronunciation EH vs. AA Vowels

In this American English pronunciation video,
we’re going to compare the vowels EH and AA.

First, let’s start by comparing profile pictures
of the two sounds.

Here you’ll see the EH as in BED vowel on
the left, and the AA as in BAT vowel on the

right. For the AA vowel, you can see that
it’s the back part of the tongue that raises

up towards the roof of the mouth. For the
EH vowel, it’s the mid/front part of the tongue

that is stretching up. Also, for the AA, you
can see that the jaw drops just a little bit

more.

So, for the AA vowel, the tongue is raising
here. AA. And for the EH vowel, the tongue

is raising more here. EH. So, here for the
AA and here for the EH.

AA, EH. When comparing the two sounds in isolation,
you’ll also notice that the jaw does not drop

as much for the EH sound, as the front part
of the tongue is raising towards the roof

of the mouth. AA, EH.

There’s a difference in the lip position as
well. For the AA vowel, you may find that

you get a more accurate sound if you lift
a little bit here with the top lip. AA, AA.

Whereas, for the EH sound, the lips remain
very relaxed and neutral, EH, EH. Now we’ll

see the two alternating up close. AA, EH,
AA, EH.

To close, a few minimal pairs. Bat, bet. Capped,
kept. Jam, gem. Tack, tech. Rack, wreck.

I hope this video has made the difference
between these two sounds a little more clear.

That’s it, and thanks so much
for using Rachel’s English.

在这个美式英语发音视频中,
我们将比较元音 EH 和 AA。

首先,让我们从比较
这两种声音的头像开始。

在这里,您将看到左侧的 BED 元音中的 EH
,以及右侧的 BAT 元音中的 AA

。 对于 AA 元音,你可以看到
它是舌头的后部

向上抬起到嘴巴的顶部。 对于
EH 元音,舌头的中部/前部

向上伸展。 此外,对于 AA,您
可以看到下巴稍微下降了

一点。

所以,对于 AA 元音,舌头
在这里抬起。 AA。 对于 EH 元音,

这里的舌头抬得更高。 嗯。 所以,这里是
AA,这里是 EH。

啊,嗯。 当单独比较这两种声音时,
您还会注意到 EH 声音的下巴并没有下降

那么多,因为
舌头的前部向口腔顶部抬起

。 啊,嗯。

嘴唇位置也有差异
。 对于 AA 元音,如果上唇稍微抬起,您可能会发现

声音更准确
。 啊,啊。

而对于 EH 声音,嘴唇保持
非常放松和中性,EH,EH。 现在我们将

看到两者近距离交替。 AA,EH,
AA,EH。

关闭,一些最小的对。 蝙蝠,打赌。 封顶,
保留。 果酱,宝石。 钉钉,技术。 机架,破坏。

我希望这个视频能让
这两种声音之间的区别更加清晰。

就是这样,非常
