Driven by policies and social needs，smart speakers and related smart manufacturing industries have gained development opportunities. From the perspective of China’s smart speaker market，since 2016，China’s smart speaker sales have grown rapidly，with a growth rate over 110%. The sales scale in 2020 is expected to be close to 9 billion yuan. Although smart speakers are currently iterating for a better human-computer interaction experience，they still face negative issues such as inaccurate speech understanding，poor usage scenarios and insecure user information. Therefore，it is necessary for smart speakers to take advantage of new opportunities such as 5G business and the development of the Internet of Things to develop into a new field of internet traffic competition.
