Actually it was for something else, but voice acting is voice acting, excluding the programming.
Rather than chase up after people who said they'd do it, I think a better way of doing it would just to post the lines required (with a link to a relevant recorder) and then wait for people to submit the .wav files, then (hopefully) you get a selection of files.
If that worked, hell would freeze over. I've worked with a LOT of communities, including a few large community projects, and the community has a bad habit of
not doing anything EVER. in addition, the same people need the same voices, so random people can't just do 1 line, they have to take the whole bunch, which further discourages anyone from doing it.
If no one does it then it's a bit of a sad reflection on the community. Also I suppose if none of the recordings are professional enough then it reflects poorely on the programmer.
Quality of the recording has nothing to do with programming. Nada. Zilch. Zippo. Zero. Nothin. Its completely dependent on the recorder and the editor. If its a bad mic --> bad recording. An editor can fix up a recording somewhat, but generally if its bad, its bad, and who knows, the random person you met on the forum could live in Peru.
