01 【发音进阶】 Assimilation of t and p 发音同化 t -> p

Tim
Hi. I'm Tim and this is my Pronunciation workshop. Here I'm going to show you how English is really spoken. It'll help you become a better listener and a more fluent speaker. Come on, let's go inside. Here's a question for you: When is a tea not a tea? Well, this is the answer. What is it? And what colour is it? Let's go to the streets of London to find out.

Now the word 'white' ends in the sound /t/ doesn't it? Or does it? Let's have another listen.

In fluent speech, if one word ends in a /t/ sound and the next word begins in a /p/ sound, the /t/ is pronounced slightly differently. In fact, we pronounce it as if it were almost a /p/ sound. So 'white piece of paper' becomes 'whi(te) piece of paper'. Let's take another look, this time in slow motion:

Interesting, hey? This is an example of how sounds change in everyday speech - and it's called assimilation. Here are some more examples:

Examples
There are lots of grea(t) parks in London.
I love spli(t) pea soup.
I ha(te) potatoes.
My ma(te) picked us up from the airport.

Tim
Right, so, you've heard the examples, and now it's your turn. Are you ready to have a go? Listen and repeat.

Examples
There are lots of great parks in London.
I love split pea soup.
I hate potatoes.
My mate picked us up from the airport.

How did you get on? Great. If you want to hear more about this topic, please visit our website bbclearningenglish.com. That's about it from the pronunciation workshop this week. Bye bye.

Did you just see…? I could have sworn it was… You know, sometimes I think I have a split personality!
