You can do this using the SWS resource window.
I have a toolbar button that pushes out a wav of-20dB pink noise.
You can even do it via the selected track or bypassing everything I think too.
I think I just loaded up the wav into the first resource slot and then found the corresponding action in action window to assign it to either a key or a toolbar.
Combine that as a custom action and all good
You could have it speaking back to you!
Or, look at using the great program "voice attack" where you can talk commands at the computer and have it reply when it's done it
