and carrying out fee deduction operation on the target vehicle through the digital currency account information of the personnel corresponding to the target vehicle according to the first voice feedback information and the fee information required to be paid by the target vehicle.

It can be seen that, with the implementation of the vehicle charging apparatus based on voice interaction described in fig. 4, after the identity authentication of the person corresponding to the target vehicle is successful, the digital currency account information of the person corresponding to the vehicle is obtained, and after the voice feedback information is confirmed according to the payment of the person corresponding to the target vehicle, the fee deduction operation is performed from the digital currency account information of the person corresponding to the target vehicle, so that the fee deduction operation for a correct account can be ensured, and meanwhile, the vehicle charging time is reduced, thereby improving the vehicle passing efficiency.

Example four

Referring to fig. 5, fig. 5 is a schematic structural diagram of another voice interaction-based vehicle billing device according to an embodiment of the present invention. As shown in fig. 5, the apparatus may include:

a memory 501 in which executable program code is stored;

a processor 502 coupled to a memory 501;

the processor 502 invokes executable program code stored in the memory 501 for performing the steps of the voice interaction based vehicle billing method described in embodiment one or embodiment two.
