How do we pronounce the 's' after the d in a word?

Question

For example: words, foods, goods, etc.

And if without the 's', how would the 'd' in those words be pronounced? Would it be pronounced like voiced /d/ or unvoiced /d/?

Answer 1

The 's' in those words is pronounced /z/ and the 'd' is pronounced /d/ (i.e., voiced).
