How to voice command a music player? I would like to know if is that possible to voice command music actions, like next track, and even delete track would be very nice.

My sport, rowing, doesn't allow me to interact with smartphone through hands, so, these voice commands would be extremely helpful.

In my tries, I just found listen to, which is not that interesting.

I am using Android 2.3.7 - Cyanogenmod 7.2 for Defy
I don't think you can do this with your stock player. 

After some digging I found a good app for you. It's called Voice Action Music Player

See if this suits for you.
