No, or at least not immediately. There seems to be a trend among mod makers recently to get each and every new project voiced right off the bat, which I see as very bad practice. With precious few exceptions (*looks lovingly at ST:R*), voiceacting isn't required in the least to play through a new campaign; there were many projects released in the days of 56k modems that wouldn't have dreamed of releasing a voice package. And the process of trying to arrange and coordinate multiple people into recording lines is something that can take months; on top of that, there aren't a whole lot of people in the community who are willing/able to do it. Voiceacting for a campaign can be compared to icing on a cake; you need to make the cake first before you can concern yourself with decorating it. Take your time, work on the project, get everything finished up, and then worry about trying to possibly get some actors together.
