It is nice to see a thread about this topic.
I am actually doing a voice acting course. Granted that its main focus is dubbing, but sometimes we also train for activities such as locution oriented to radio and interpretation in general. I really hope I can be cast for something like this one day.
Believe me, voice acting is a very difficult skill to train that I feel doesn’t get enough recognition (again I’m mostly referring to dubbing which has some issues of its own), and I will always support it. However that doesn’t mean that voice acting hasn’t its own limitations, adding to what was said above by @Nocturnal_Stillness one of them is that an audio medium is completely different from a text based medium. For example, audio removes the ambiguity of text, different people can have different interpretations of the same sentences, but when you are adding acting you have to pick one.
I really like voice acting and, as I said, I will defend it but sometimes it’s better to use it only when you feel it can really add something to a particular work.
By the way, if someone happens to have a particular question about what we do in that voice acting course, I’ll always be willing to talk about this subject.
