I have noticed that some Americans (not all) pronounce the word 'niche' as 'nitch' (IPA /nɪtʃ/) rather than as 'neesh' (IPA /niːʃ/).
niche Pronunciation: /niːʃ/
Why do these same people not pronounce 'cliché' with a "tch" (IPA /tʃ/) sound?
Both words are loanwords from French, but the treatment of the "ch" sound seems to be inconsistent. Is it due to the difference in accentuation?
Also, which groups of people use 'nitch' as the pronunciation for niche?
Is it wrong or can one argue for it?
As a Brit, unsure as to internal American differences in pronunciation, I was wondering if nitch is more of a western pronunciation. I have heard that it becomes more like British English as you go East.
