I am developing atn app that is using the text-to-speech capability in IOS: I am using english, swedish, norweigan, danish and finnish. The voices for all this languages have approved a lot. But there are of course difficulties to pronounce specila words and names and also som combinations or words.
Is it possible to use phonetic text to enhance this? Some text-to-speech solutions can do that. One possiblity is to add a dictionary substitutiong words for the phonetic version of it.
