Step 130, determining whether the address information corresponding to the destination information is unique, and if not, executing step 140;

Step 140: Generate prompt information; the prompt information is used to prompt to obtain the passenger's voice supplemental information again;

Step 150: Acquire voice supplement information of the passenger;

Step 160: Extract destination supplemental information from the voice supplemental information;

Step 170: Determine unique corresponding address information according to the destination information and the destination supplementary information.

Step 180: Generate a taxi order according to the unique corresponding address information.

For example, the passenger said "Help me call a taxi to Haidilao", the extracted destination information is "Hai Dian", and the address information corresponding to "Hai Dian" is multiple. At this time, the prompt message "has been queried." In multiple locations, you can ask me about Haidilao near a certain place, such as Haidilao, which is attached to Xizhimen. The passengers say “I am going to Haidilao near Sihui Bridge” to extract the destination according to the passenger's supplementary voice information. The supplementary information is “Sihui Bridge”, and the unique corresponding address information is determined according to the destination information and the supplementary destination information as “Haidilao Hot Pot Red Temple Store”, and a taxi is generated according to the unique corresponding address information “Haidilao Hot Pot Red Temple Store”. Order

Or the message “The nearest one is Haidilai Yizhuang Hualian Store. Do you confirm Haidilao Yizhuang Hualian Store as the destination address?”, the passengers said “confirmation address” and extracted the destination according to the passenger's supplementary voice information. The “Yizhuang Hualian Store” corresponding to the “confirmation” of the supplementary information determines the unique corresponding address information according to the destination information and the supplementary destination information as “Haidilao Yizhuang Hualian Store”, according to the unique corresponding address information “Haidilao Yizhuanghua” The joint store "generates a taxi order.
