Accurate, authentic pronuncation.
I haven't mastered IPA. I've tried to use the written out pronunciation piece in dictionary definitions. But that's really slow for me and then it's relying only on me -- If I forget a rule, I end up with the wrong pronuncation.
Not specific words just.. All of them. Haha. Anything I want. In typical languages related to music. Standard music languages -- Italian, German, French, Russian, Spanish, etc.
Sometimes it's more that I want a quick check on whether I'm pronouncing a word right.
And I don't always want to think. If the program spits out the word for me, that's less brainwork on my end.
