Voice Activity Detector Implementation

This is my current implementation of the VAD blocks:


Is the state machine my best bet for muting/unmuting audio in reaction the VAD Flag?  Does anyone have any idea on how to add hangtime to the end of voice detection period.  Right now the audio will cut in and out as you speak, I want to keep the audio active for a minimum of 2 seconds after voice is detected.  I can't see any clear cut way to do this with external blocks or with the VAD blocks themselves.
