Abstract: A voice priority control system in a multi-device scenario is proposed. A priority model is constructed based on information such as device functions, device status, user habits, etc., to calculate and prioritize the weights of each device. In scenarios where the target device is not clearly designated, if there exist several devices with the same name or the user does not specify the target device, this system would automatically select the device of the highest priority to respond to the user's instruction. The experimental results show that the system using the priority model greatly improves the success rate of device control, and simplifies user commands during voice interaction at the same time. Moreover, this system also solves the target decision-making problem in multi-device interaction, and further improves the smartness of voice control.
