English Sounds - The Two TH Consonants [θ] and [ð]

In this American English pronunciation video  we're going to learn how to make the two th sounds.

在这个美式英语发音视频中

我们将会学习th的两种发音

These sounds are paired together because they take the same mouth position.

因为这两个发音是用同一种地方发音 所以我们放在一起讲

TH is unvoiced meaning only air passes through the mouth TH and TH

这个音是清辅音 只有气流通过口腔

这个发音则是浊辅音 声带震动

is voiced meaning you make a sound with the vocal cords.

The very tip of the tongue comes through the teeth. The air passes around the tongue. The tongue is  

舌尖伸出牙齿 气流在舌头上冲出

舌头是需要放松的 不能用力 否则会阻碍发声

relaxed. There shouldn't be any pressure in  the mouth or a stop quality to this sound.

Just nice and easy.

这样的话 这个发音会很简单

The tongue has to easily vibrate between the  teeth so keep the tongue soft and relaxed.

舌头需要很轻松地在牙齿中震动 并且舌头是需要放松的

The lips don't affect this sound so they can  be transitioning to the next sound. For example  

嘴唇不影响这个发音 但是嘴唇可以为下一个发音做准备

例如 在THR辅音连缀中

in the thr cluster the lips will round a  little bit for the r as you make the th  

嘴唇会因为R音变圆（o型）

Three, three. Be careful with the tongue tip. Make sure it doesn't come too far forward. 

三

要注意舌尖

不要把舌头向外伸出太多

It's just the very tip that should come  between the teeth to make the unvoiced th,

要注意 就只是舌尖伸出来

但是对于清辅音th

the tongue tip absolutely has to come through the teeth.

舌头一定要伸出来

But the voiced th can be different. When it's  in an unstressed quick word like these or the  

但对于浊辅音th就不一样了

当有些词是浊辅音小词的时候

例如 these 或者 the

The tongue tip doesn't have to come through the  teeth. It can press behind the teeth make sure  

舌头可以放在牙齿后面

the tongue isn't at the roof of the mouth or  pointing down but pressing right in the middle

要注意舌头不可以在口腔顶端或者下端

而是在牙齿闭合时的中间发力

where the teeth come together. If it's not in the right position the sound will be wrong.

如果不是在这个位置 这个发音就错了

这些

This tongue shortcut works in these words because  they're unstressed so when you don't bring your  

因为这些词是清辅音（小编：其实是浊辅音） 这些小技巧可以派上用场

tongue tip through the teeth it allows you to  make these less important words quickly. These,  

所以如果你不把舌头伸出来 这些技巧会让你的发音更快

the. Let's look at these sounds up close  and in slow motion. Notice how it's just  

让我们来就近距离慢放地看一下这些发音

要注意 就只是舌尖伸出来 舌头是放松的

the very tip that comes out of the teeth.  The tongue is relaxed the teeth surround it  

but they're not clamping down on it. The lips  and face are relaxed throw notice how the lips  

而不是夹紧舌头

嘴唇和脸是放松的

扔

注意看当发清辅音 把舌头伸出去的时候 嘴唇是如何为R音所产生变化的

are starting to flare for the r as the tongue  comes through the teeth for the unvoiced th.

生日

Birthday. Keep in mind when you only stick the  very tip of your tongue out the movement into  

要注意 当舌尖伸出来 发临近的音不是像你想象的那么难

other sounds isn't as hard as you might think. Watch the tongue tip come in and flip up for the d.  

请观察舌头在做发D音的准备（收回口腔内并翻转）

This is a quick move of the tongue that you can  practice over and over to make it more natural.

你可以一直练习使其变得越来越自然流畅

Brother. Tongue tip through the teeth for  the voiced th lips and tongue are relaxed.

兄弟

舌尖通过牙齿来发浊辅音th

舌头是保持放松的

值得

Worth. Ending in the unvoiced th. Again  the lips and tongue look very relaxed.

在词尾有清辅音th

同样地 舌头是需要放松的

Remember to keep your tongue relaxed  and soft when you practice this sound. 

要记住 当你练习的时候 舌头是软的 放松的
