/s/…/z/…/s/…/z/…/s/…/z/…

These sounds are both alveolar, fricative consonants. However, /s/ is a voiceless consonant and /z/ is a voiced consonant. If you are pronouncing /s/, your vocal cords should not vibrate. At the end of a word, the vowel before /s/ will be shorter than the vowel before /z/.
 
 
You can hear the difference between /s/ and /z/ in these words.
