"s"

[hathu]

hi, everyone:
can you guys tell me more about how to pronounce "s".
For example:

bakes or temps or plays or catches

[5jj]

Try here, and come back if you have any questions:
Pronunciation of verbs (3rd person singular) ending in -s

[BobK]

There are three sounds there. The first two have /s/ - a hissing sound like a snake. (Note that 'bakes' is a single syllable, so the 's' follows an unvoiced consonant, as does the 's' in 'temps').

The third has the sound /z/. Where the tongue goes is the same, but the sound is voiced. (For the difference between voiced and unvoiced consonants look here: Voiced and unvoiced consonants | TeachingEnglish | British Council | BBC )

The fourth has the sound /ɪz/.

Have you followed the links Bob and I provided?
If they do not answer your doubts, can you explain what you think the problem is?
