I want to add my 5 cents to the previous answers as this is the first result on this question from Google.
The right symbol there is /ɲ/
, see. That's the sound for Czech/Slovak ň, Polish ń, Spanish ň, Italian gn, Rusian нь and so on. According to the previous link, the sound is not present in English and you don't find it in a dictionary neither as far as I know.
Therefore, I wouldn't trust answer of English native speaker on this topic as they don't have ň, so they can't really tell difference between n /n/
and ň /ɲ/
:-)
According to pronunciation of knew homophone Wiktionary Americans tends to say /n(j)uː/
, while Britons /ɲ(j)uː/
. I think British pronunciation is actually result of relaxed pronunciation – when you try to pronounce /nju:/
neglectfully, you actually merge n and j and result is /ɲuː/
.
note: Please, notice that ɲ symbol is actually combination of letter n and j, for an obvious reason.
