-t + you/your，变音成 /ʧ/

In fluent speech, when one word ends in /t/ and the next begins with a /j/ sound, like 'you' or 'yours', then the two sounds come together and change to /ʧ/. So 'meet you' becomes /miːʧuː/. This is an example of assimilation. Now you might remember that in a previous video I mentioned that the /t/ sound can disappear in between two consonants. Well, this can still happen if the next word is 'you' or 'your', but it's more usual for the /t/ to change to /ʧ/ in this case. Here are some more examples.

1. It's nice to meet you.

2. It won't suit you.

3. Don’t you want to come to the park?

4. I bet your boss doesn’t know.

5. Can I get you anything?

6. You can't always get what you want.

7. get you = gotcha! /ˈɡɒtʃə/ [= I'm gonna get you. I will hunt you down.]
