Hello, I'm John Russell.

你好，我是約翰-羅素

Some consonant sounds are like coins.

有些輔音就像硬幣。

A coin is usually made from one material, but the front and back look different.

一枚硬幣通常是由一種材料製成，但正面和背面看起來不一樣。

There are consonant sounds that are also like that.

有輔音也是這樣的。

Today.

今天的。

We will explore how coins are like certain kinds of sounds in American English.

我們將探討硬幣在美式英語中是如何像某些種類的聲音。

In previous videos, I talked about stop consonant sounds sounds that involves stopping the air for a brief amount of time.

在以前的視頻中，我談到了停止輔音的聲音，涉及到停止空氣的短暫時間。

I also talked about voicing movement of the vocal cords.

我還談到了聲帶的發聲運動。

But how do stop consonant sounds connect with voicing?

但停頓輔音如何與發聲聯繫起來呢？

There are six stop sounds in American English.

美式英語中有六個停頓音。

They are, but to yeah, car Good.

他們是，但到是，車好。

And let's see how these sounds connect with coins.

我們來看看這些聲音是如何與硬幣聯繫在一起的。

First, we have the PA and PA sounds.

首先，我們有PA和PA的聲音。

These sounds are made out of the same basic material.

這些聲音是由相同的基本材料製成的。

They both require you to use both of your lips.

它們都需要你用兩片嘴脣。

But so what is the difference between them?

但是，那麼它們之間有什麼區別呢？

Voicing is voiceless and but is voiced.

發聲是無聲的，但卻是有聲的。

It's like two sides of the same coin heads and tails voiced and voiceless.

這就像一枚硬幣的兩面，頭和尾有聲和無聲。

The other four stop sounds act in the same way.

其他四個停頓音的作用也是一樣的。

Now the problem with stop sounds is that it can be difficult to tell if your vocal cords are moving.

現在停音的問題是，很難判斷你的聲帶是否在動。

This is because stop sounds can't really be made longer.

這是因為停止的聲音真的不能做得更長。

After all, they involve stopping the air.

畢竟，它們涉及到停止空氣。

But there are important patterns in how English speakers use stop sounds with vowels.

但是，在英語使用者如何使用元音的停頓音方面，有一些重要的模式。

But that will have to be a subject of a future video.

但這必須是未來視頻的主題。

That's all for today.

今天就到這裡吧。

Keep up the good work.

繼續保持良好的工作。
