I've always found my own voice to be kind of weird before I started podficcing (I couldn't listen to my own voice in videos and whatnot without cringing a bit and think, "Wait, I sound like that?" X3); and I also tend to talk too fast -- I still talk a bit fast, but podficcing has helped me articulate a bit more, and be more aware of...I guess, the pacing of my speech and my voice in general? It's helped with giving presentations a bit. XD So, yay, other benefits to podficcing! I'm glad you're giving it a shot! :DDD If you need a cheerleader or a beta-listener or whatever, feel free to prod me!
