Do you do any pre-processing on the audio input to filter out background noise? I notice that in the demo video, you're in a quiet room.

I can run PocketSphinx on Raspberry Pi fine, and the recognition is fine too - as long as there isn't too much background noise. When I say 'computer open curtains', for example, it open my curtains through my HA system; but the motors in the curtains make some noise, so I can't say 'stop' halfway through because it just won't pick it up. Another part of the problem is that audio chunks are fed to PocketSphinx by recognizing end of sentence through silence in the input; so when the curtains are still going, it doesn't recognize that the command has stopped and the audio should be passed into PocketSphinx.

So, how does Snips deal with this?
