I would think it would be possible and even beneficial to dedupe the data (15m homes x NFL broadcast, for example). Link a list of each echo's text conversion given similar data but perhaps different background noise. Or maybe getting data from multiple echos in different homes at the same time allows for "noise" filtering (people asking different things while the same background noise is present).
