Clearing Retained Audio

Is there a way to do this ? I reatain the audio by calling
SetAudioOptions as mentioned in SDK whitepapers. Is there a way to
clear this audio lets say after some timeout? The Reason i ask this is
sometimes sapi behaves weirdly and I don't events like true or false
recogntion for a long time. And when I do get one the audio stream
that I get is very very long. So I just wish to purge the buffer from
time to time. Is there a way to do such thing?

You can discard the audio by calling ISpPhrase::Discard(SPDF_AUDIO). See 
here for example code:

You'll just need to figure out when you want that to happen, and then call 
that method.
