Is there a sound name for 's', 'z', 'sh', 'ch' and 'j'
A Wikipedia page on English phonology has the following:
- s: /s/ unvoiced alveolar fricative
- z: /z/ voiced alveolar fricative
- sh: /ʃ/ unvoiced post-alveolar fricative
- ch: /tʃ/ unvoiced post-alveolar affricate
- j: /dʒ/ voiced post-alveolar affricate
There’s also the terminal sound in a word like luge (the tobogganing sport):
- /ʒ/ voiced post-alveolar fricative [that is, related to /ʃ/]
However they are all sibilants and listed as such in Wikipedia.
