Are you trying to sound more natural when you are speaking English?

你是不是想讓你的英文聽起來更自然呢？

現在進行式

Then I think you are looking for some assimilation rules.

那我想你正在找一些同化規則。

Assimilation is when one sound changes because it's anticipating the next sound.

同化是指一個音因為預期下一個音而發生改變。

These change based on place where your tongue is and your lips are when you're making a sound, manner, how the sound is made, how the air is moving and voicing.

這些改變會根據你發音時舌頭和嘴脣的位置、發音方式、氣流的移動以及聲帶的振動而有所不同。

For today we are going to be talking about place assimilation with a nasal sound.

今天我們要來聊聊關於鼻音的處所同化。

So we have the nasal sound N and when we make that sound, the tip of the tongue is behind the top front teeth and air is moving out of the the nose.

所以我們有鼻音 N，發這個音的時候，舌尖會放在上門牙後面，氣流會從鼻子出來。

When this sound is followed by sounds that are made with our lips, P B M then what we are going to do is keep that place and we are going to change the place of the N to a lip sound so that is going to become an M.

當這個音後面接著是用嘴脣發出的音，像是 P、B、M 的時候，我們就會保持原來的發音位置，把 N 的發音位置改成脣音，所以它就會變成 M。

What we are going to keep is we are going to keep that nasality of the end N.

我們要保留的是 N 這個鼻音的鼻音特徵。

Air comes out of the nose, we're going to keep that nasality but our lips will be closed so the sound will sound like an M.

氣流從鼻子出來，我們會保留這個鼻音，但嘴脣會閉起來，所以這個音聽起來就會像 M。

So we have a lip sound after this N. The N will change to an M.

所以這個 N 的後面接了一個脣音。N 就會變成 M。

So instead of saying on point I might say on point.

所以與其說 on point，我可能會說 on point。

Instead of saying in bed I might say embed and instead of saying in my I might say in my.

與其說 in bed，我可能會說 embed，然後與其說 in my，我可能會說 in my。

Now people will sometimes use assimilation and other times they will not depending on how they are connecting words in a sentence.

現在大家有時候會使用同化，有時候則不會，這取決於他們在句子中如何連接單字。

So I can still say on point and that is totally fine.

所以你還是可以說 on point，這樣完全沒問題。

I can still say in bed that is totally fine and in my totally fine.

你還是可以說 in bed，這完全沒問題，in my 也一樣。

But a lot of times I do use assimilation and then my sound changes to point embed in my.

但很多時候我會使用同化，然後我的音就會變成 point embed in my。

So let's give those a try on point embed in my.

所以我們來試試看 on point embed in my。

I know people are going to notice the difference.

我知道大家會注意到這個差異。

I hope you enjoyed this assimilation lesson.

It's a little bit different so let me know your thoughts.

這有點不一樣，所以讓我知道你的想法。
