[Speex-dev] Behavior of Speex VAD algorithm

I have two questions regarding the Speex VAD mechanism:
1) I noticed a delay of about 0.4 seconds in recognizing the end of speech
(the point where there is a transition from speech to silence). Is there
some way to prevent this delay?
2) When the recording immediately starts with voice rather than silence,
Speex is confused for a few seconds, and usually only recovers after the
first interval of speech ends. Is there someway to prevent this problem? I
thought of prefixing each stream with a short recording of silence. Is there
a better way?
Thanks for your help!
