Pronunciation of h in Serbian
"The phoneme /x/ (written as h) has been volatile in eastern South Slavic dialects. In Serbian and
some Croatian dialects (including some of those in Slavonia), it has been replaced with /j/, /v/, or
elided, and subsequent standardization sanctioned those forms:" ~ wikipedia https://en.wikipedia.org/wiki/Comparison_of_standard_Bosnian,_Croatian,_Montenegrin_and_Serbian#Accentuation
Now I understand that they are written as j or v if they are pronounced so, but how is it pronounced when it is still written, for example hteti.
