My interest in sound design and music production took a surprising turn and I now spend my weekends studying alien vocalization. More specifically, figuring out how to synthesize believable alien vocals and make them expressive and customizable enough to be a tool for anyone who needs that sort of thing for their creative work.
I am releasing everything for free and the first "instrument" and sample pack with previews/videos is already available here: https://neuromorph.gumroad.com/l/alien_vocalization_study_1
