Why does the 'я' sound unstressed and more like a 'є' sound ?
By stressing "я" you slightly change the meaning of the question. It sounds like you are not sure if the question is about your likings or someone else's and you are clarifying it.
The unstressed "я" does not sound like "є" to me.
"What do I dislike doing?", why not?
I do not have access to a Ukrainian alphabet
Why it can't be " what i do not like"
