Can you trust a smart speaker？

-
Q1: Do you have a smart speaker at home?
A  : Yes, I have two smart speakers. One of them is Apple’s Siri, which helps me operate my phone better. The other one is TmallGenie.  By giving it voice indications, It can control domestic appliances, play music, top up my phone and so on. They all bring convenience to my life. 
Q2: What is a smart speaker？
A   : A smart speaker is a type of wireless speaker and voice command device, with an integrated virtual assistant that offers interactive actions and hands-free activation, with the help of one "hot word" (or several "hot words").


Q3: How does a smart speaker work?
A  : Basically, you give it a voice command and it does what you want. According to the research, although each smart speaker system is slightly different, when looking at how they work, typically the smart speaker listens to all speech and awaits a “wake word.” Also, it will analyze and  learn how you speak so the system can provide a better service.
