Our next word is ITEMS with a flap T.

我们下一个词是带弹 T ITEMS。

So you'll hear literally with that flap T sound, right?

你能听到“确实”这个词弹 T 对吧？

Can you hear that flap T sound when I say it?

我说时候你能听到里面弹T吗？

Now can you hear that flap 'T' there? It sounds more like a 'D'. 'Whatta', 'Whatta', 'Whatta' and then again 'later', 'later'.

你们能听到这里弹‘T’吗？听起来更像是‘D’。‘Whatta’，‘Whatta’，‘Whatta’，然后是‘later’，‘later’。

In some forms of American English, the flap occurs for ''t'' in words like dirty and sorting, after r -colored vowels in a stressed syllable.
