Default [Q] Autovoice (Tasker) during locked screen

Good morning all...

I've recently discovered how awesome Tasker is, and I've started having a LOT of fun with programming it.

One particular program that I'm proud of:
1) Incoming text sender is read aloud
2) Autovoice is enabled for 5 seconds
3) IF it receives the command "read message", it reads the message out loud

I've got this working quite well... except for when the screen is locked, which makes it rather useless.

Does anyone have a way that autovoice will be recognized if the display is off (and preferably when the screen is locked - as I'd be using this mostly in my car)?

Thanks
