No, there is no voice acting, but steam recommended to add it if in any case there will be VA in the future, and since I'm thinking about it for a while, I added it to the steam page.
Right on, the character design looks pretty well done, so definitely looking forward to giving it a shot, and would love to see VA in a future update.. Not trying to name drop another title, but I plaid Lust Theory when it was released which has it (I actually think they just hired two women to do all of it but it actually works seeing as you're never hearing them talk at the same time) but it really added to the story immersion.
