With the increasing popularity of intelligent car machines, more and more cars are equipped with intelligent voice assistants. For "intelligent voice system", we will judge the performance of voice interaction system in terms of voice recognition rate, response speed and controllable functions through the following four fixed scripts.

1. I'm a little cold/I'm a little hot

2. Open the window/open the driver's window/open the sunroof

3. I want to listen to "XXXX" (song name)

4. I'm going to Lunyang Mansion
