The driver uses the "(audio_mode 'shutup)" command. The documentation for it is 
as follows:

   (audio_mode 'shutup)
          Close the audio down now, stopping the current file being played
          and any in the queue. Note that this may take some time to take
          effect depending on which audio method you use. Sometimes there
          can be 100s of milliseconds of audio in the device itself which
          cannot be stopped.

I wonder if this "some time" thing is what you're seeing. Maybe speaking 
something longer with, say, a command like SAY_BELOW would be a way to test 
this.
