Not suggesting for one second I'm the first to have this idea, but I've just spent a good few hours searching for a sound clip of a woman saying "Warning! Oxygen levels critical!"
As you might expect I drew a blank everywhere. And then the solution hit me.
This would work best if your game uses limited dialogue, but if you go here:
text-to-speech you can type in your lines and have a variety of voices speak it out loud. The voices sound quite authentic and there's a variety of effects that can be added.
Imagine how good this could be if you're making a sci-fi game with an android as one of the characters?
Simply hit the record button in Audacity, run the text-to-speech, and then trim it up in Audacity before exporting as an mp3.
In my case it was perfect, as I needed an automated voice anyway. I added the reverb effect and it sounds very good indeed.
Comments
On reflection and having played around with a few of these text-to-speech programs (of which the one I linked to sounds the most natural) I'm not sure they'd be particularly immersive, especially if you want to use dialogue of any length.
As I say it would be perfect if you wanted a talking android/mechanoid/robot, but not so much for humans.
