Checking if speech finished?

[Andy Dent <dent@oofile.com.au>]

If you use the Speak command, which does asynch speech on Mac and  
Windows, is there any way to tell that it has finished?
One of the options in rbKarel http://code.google.com/p/rbstuff/wiki/rbKarelOverview 
 is to speak every action as it occurs.
This implies we would like the robot to not proceed until the previous  
action is completed, so I'd like some way to poll the speaking status  
or otherwise block on speech completion.
As this is an open source project, it can't rely on any proprietary  
plugins for this option.
thanks
