The correct pronunciation of "-ed" at the end of the verb "played" is /d/. This is because the verb stem "play" ends in a voiced consonant (/d/). When a verb stem ends in a voiced consonant, the "-ed" ending is pronounced as /d/. For example:
- loved
- hopped
- danced
- cooked
If the verb stem ends in an unvoiced consonant (except "t"), the "-ed" ending is pronounced as /t/. For example:
- stopped
- kicked
- watched
- laughed
