The /s/ sound is normally spelled with <s> or with <c> before <e>, <i> or <y> in cyst. We also see <sw> in sword and <ps> in psalm. The /h/ sound is spelled with <h>, or <wh> in whore. Notice how the homograph sow makes pairs with hoe and how.
This is a contrast between an alveolar sibilant fricative and a glottal fricative, both voiceless. It can only occur initially or medially. It may cause problems especially for speakers of languages which do not have an initial /h/, such as French and Spanish.
