add default apps to Google voice function?

[jrsharp70]

I really want to use amazon mp3 with the Google voice control on my gingerbread phone... but it won't give any options except Google play, music player, or YouTube. Same thing with the navigation control and text messages.

Anyone had any luck changing the default options?

Oh, and headphone controls for music would also be a bonus if anyone knows how to accomplish that.

Thanks in advance!
