Here is what I have found online:

Automatic mixing of either input signal with output to
avoid silences. Choices of two release times.

In order to prevent unpleasant staccato effects, 
silence  bridging  (sometimes known  as  `pause 
stuffing'!)  must  be used.  Depending upon the
vocoder, a bridging signal, which is derived either
from the original speech signal of from the excitation
signal, and the amplitude, harmonic content and attack
and decay times of which can be varied, is mixed into 
the  pauses, thereby  providing an audible output
signal.
