say and afplay were exactly what I needed. Thanks.
I've taken a battery script and made it my own to tell me when my battery is below a certain charge on my MBP when I'm not running on the charger. I do that like once a week to keep my battery healthy, and sometimes I forget and it goes dead, which I don't want. So, say will be helpful for just saying the battery is running low. Afplay was able to play all the other sound files I have. Again, thanks.
