We've used Replica Studios to create a voice pack with 101 unique voice lines for an RPG style game. Each line is performed in three different styles. These are perfect for using as placeholders or prototyping your game.
If one of the lines doesn't quite work, Replica Studios is offering a free trial with 30 minutes of voice generation, so you can edit any of these voice lines or create your own.
