"s" in ancestors pronounced as /z/? or /s/?

[NewHopeR]

Context:

I stand here today humbled by the task before us, grateful for the trust you have bestowed, mindful of the sacrifices borne by our ancestors.

It's more like a "z" when I say it.

Same here.

if a words ends in a vowel in the case of ancestors ' the schwa' then the final 's' is pronounced /z/. I suggest you refer to "The English Pronouncing Dictionary" by Daniel Jones

Daniel Jones!
Good suggestion.
Thanks.

Also, the simple rule is, the audible phoneme (sound) immediately preceding the final S determines whether the S is voiced or unvoiced, as the S simply follows its pattern:

dog - dogs (/z/ because /g/ is voiced)
cat - cats (/s/ because /t/ is unvoiced.)
