Vocal Parts

Hello,
I want to create a demo of a song of mine written in MuseScore. The score of the song has a soprano vocal part, an alto vocal part and a tenor vocal part. Currently, the parts are played by an oboe, an English horn and a bassoon. I would like the three vocal parts to be "sung" by real human voices so that the demo will be more realistic and more likely to please the listener. Of course, I can hire three vocalists to sing the parts but that can be very expensive and very time consuming. Can MuseScore currently add real human voices to my MuseScore score or is that feature something that can be added in the future?
