Self-service audio guide machines play an important role in tourism.

    Scenic spots and exhibition halls are now usually using self-service audio guide, because they can provide tourists with detailed information about all aspects of the scenic spots in clear and vivid voices, replacing the traditional oral explanation method of manual tour guides. Tourists can pause and continue to listen to the explanation at any time according to their own rhythm, without being disturbed by others, and do not have to worry about not keeping up with the speed of the tour guide. Self-service audio guide also have different appearances and various functional advantages. There are tour guides with large screens that can display pictures and text materials related to scenic spots, such as historical photos and videos of scenic spots, so that tourists can understand the characteristics of scenic spots more intuitively and comprehensively.

      These graphic materials usually cooperate with the voice explanation content to enhance the explanation effect. Self-service audio guide can also set up positioning navigation functions, use positioning modules to determine the specific location of tourists in the scenic area, and provide accurate navigation instructions, telling tourists the best route to the next scenic spot, and how far away from the destination, etc., so that tourists can plan their own tour routes and avoid getting lost. The self-service audio guide machine has a high degree of autonomy. Tourists can tour according to their own wishes and pace. They don't have to be restricted by the itinerary of the tour group and the progress of the guide's explanation. They can stop when they want and leave when they want, and have more autonomy in choosing.
