This response is no inadequate that it is almost laughable.

They claim that their experts can listen to a small number of recordings of human speech directed at their devices. However, there is no telling what people might be speaking to their Google devices. I don't use Google Home, but given that it allows one to set reminders, etc., I would think that people could be saying pretty sensitive things, including phone numbers, addresses, credit card numbers, etc. which combined together can identify them uniquely or at least allow those bits of information to be misused.

Also, embedded in the figure of 0.2%, mentioned for the percentage of spoken interactions listened to, is the assumption that it is a very small number. However, that number implies that 1 out of every 500 interactions are listened to. For a family of 4 owning a Google Home, the number of spoken interactions with it in a year would easily run into thousands. Therefore, the experts at Google are listening to at least a handful of interactions every year for each family. Given the speech-to-text state-of-the-art, if these recordings are being converted to text and being stored, it would not be hard to group the recorded interactions per family and derive some identifiable information about them from it.
