I asked Siri, Alexa and Google Assistant if they're spying on me -- here's what they said

A lot of people are worried that voice assistants like Amazon (AMZN)'s Alexa, Apple (AAPL)'s Siri or the Google (GOOGL) Assistant are spying on us at home. All three companies have said the assistants are not listening all the time, but only listen for a wake word -- or perhaps hidden commands humans can't hear. So I asked all three voice assistants if they're spying on us, just for kicks. Here's what each one said. Here's what Amazon Alexa said: "I only send audio back to Amazon when you activate me.
