That's not true. Amazon can have a significantly more accurate classifier running on their backend that processes the transmitted audio. And this classifier can be more accurate due to both more computation and it would have access to the entire data stream, not just the initialization words. You would never know that your data was sent to Amazon and then ignored.

But unless you have multiple devices, those make up a relatively small proportion of requests, and hence most of the time false positives is something they have a strong incentive to stop because it causes negative user experiences. [If you have multiple devices it will happen "all the time" when a request is genuinely meant for a Alexa device but more than one device hears the request, but then it has no UI effect - one device will usually answer, and the other(s) will stand down; this is by no means perfect, but it works reasonably well]
