How to tell /s/ and /z/ apart

Practice the difference between the voiceless fricative /s/ and the voiced fricative /z/.

/s/
Voiceless S

sip /sɪp/

A voiceless fricative made with the tongue near the ridge, no voice.

Lỗi thường gặp: Learners may voice /s/, making sip sound like zip.

/z/
Voiced Z

zip /zɪp/

A voiced fricative with the same tongue position as /s/, voice on.

Lỗi thường gặp: Learners may devoice /z/, making zip sound like sip.

  • /s/ is voiceless: sip, sue, ice.
  • /z/ is voiced: zip, zoo, eyes.
  • Same tongue position for both.
  • Touch your throat — /z/ vibrates.
