Maybe not at this point, but if they spent some time writing better filtering and speech recognition algorithms it might be able to achieve a much higher accuracy. Since it's currently so easy to get sensor data on android phones there's a fairly strong incentive for people interested in eavesdropping to do so. It's pretty cool, anyway
