文字稿
Did you know these two letters can be pronounced in three different ways?
They can be /d/, /t/ or /ɪd/. Here's how to find out which.
First, feel your neck. If a sound makes it vibrate like /d/, then it's voiced. If it doesn't like /t/, then it isn't.
Where 'ed' comes after a vowel or a voiced consonant, then pronounce it as /d/, which is a voiced sound. Played, used.
If you have 'ed' after an unvoiced sound, then it sounds like /t/ – an unvoiced sound. Looked, helped.
If you have 't' or 'd', then 'ed' becomes /ɪd/ – it's just easier to say. Wanted, needed.
So, if 'ed' comes after a voiced sound, then it's voiced. If it comes after an unvoiced sound, then it's unvoiced, and if it comes after /t/ or /d/, then it's /ɪd/.
