That might be the case, but while "news-teller" is not a standard or formally recognized English word, it is likely that many English speakers would still recognize and understand its meaning, more so than "herald", in my opinion. I am fine with "reporter", too. FWIW I provided a literal translation.

Check out my other replies if you are interested[1].

In any case, language evolves. :)
