Yuan Xiaolin, President and CEO of Volvo Cars Asia Pacific, complained about the function of intelligent voice control for cars。For example, Yuan Xiaolin said that the user shouted to the voice control function in the car, please open the sunroof. After two seconds, the voice system responded with "OK." After another second or two, the sunroof of the vehicle opened。Then everyone was very excited and said that the car was very smart; but in fact, the function that can be achieved in 1 second with physical buttons, now it takes 4 seconds to use voice control, what is the meaning of this setting, and what is it? Need?
