When the voice recognition results of the preset number in the voice recognition result list are respectively sent to the first terminal equipment according to the sorting results, the next voice recognition result is sent after the user clicks to confirm or cancel, if the preset number is 3, if the voice recognition results are not confirmed by passengers three times continuously, guiding is abandoned; or if the voice recognition result confirmation information is not received within the preset time after the voice recognition result is sent, the guidance is abandoned.
Step 103, obtaining information of a destination according to the voice recognition result confirmation information, planning path information from the position of the first terminal equipment to the position of the destination according to the information of the destination, and sending the path information to the first terminal equipment.
The indoor guiding method based on voice recognition provided by the embodiment of the invention can be used for indoor guiding, and the information of the destination which the user wants to go can be obtained according to the user inquiry voice information. For example, the user query voice information includes destination-related information. And the server plans path information from the position of the first terminal equipment to the position of the destination according to the information of the destination, and sends the path information to the first terminal equipment.
According to the embodiment of the invention, the voice recognition is carried out according to the user query voice information, the voice recognition result list ordered from high to low according to the matching value is obtained through query matching, the voice recognition result confirmation information sent by the first terminal equipment is received, the destination information is obtained according to the voice recognition result confirmation information, the route information planning and the sending are carried out, the accurate acquisition of the user destination information is realized, and the effective and convenient indoor guidance is realized.

The user query voice information includes location information such as "out of the way", "how out of the way? "," where the departure gate is ", etc. The server performs voice recognition on the user query voice information, converts the user query voice information into text, extracts location keywords such as 'stop entrance', and performs matching query in a location database according to the location keywords. The location database stores names of various locations which can appear when the indoor guidance is performed. And descending and sorting the query results according to the matching degree value to obtain the voice recognition result list, wherein the voice recognition result list comprises a sorting list of the destination points to be selected.
On the basis of the embodiment, the embodiment of the invention provides a method for acquiring a corresponding voice recognition result list when the user inquires that the voice information comprises the location information, which is beneficial to realizing destination location guidance.
Further, based on the above embodiment, the obtaining the information of the destination according to the voice recognition result confirmation information includes: if the voice recognition result confirmation information corresponds to a plurality of places, further judging whether the user inquiry voice information contains limiting conditions or not; if the voice recognition result confirmation information is included, selecting one of a plurality of voice recognition result confirmation information corresponding places as the destination according to the limiting condition; the limiting conditions comprise one of the minimum number of queuing people, the shortest distance and the shortest time; the method comprises the steps that a place with the least queuing number is obtained through analysis of queuing information of people collected by video collecting equipment arranged at each place; and if the voice recognition result confirmation information does not contain the voice recognition result confirmation information, selecting one of the corresponding places of the voice recognition result confirmation information as the destination according to a preset rule.
After obtaining a voice recognition result list ordered from high to low according to the matching value, the server sends the voice recognition results with the preset number in front in the voice recognition result list to the first terminal equipment. If the user query voice information includes location information, the voice recognition result also includes location information. After receiving the voice recognition result confirmation information sent by the first terminal device, the server can acquire the destination to which the user wants to go. If the server finds that the locations corresponding to the voice recognition result confirmation information are multiple, the server further judges whether the user query voice information contains limiting conditions, wherein the limiting conditions can be, for example, the minimum queuing number, the minimum distance, the minimum time (the minimum time from the position of the first terminal to the destination), and the like. If the server finds that the user inquiry voice information contains the limiting condition, one of the positions corresponding to the voice recognition result confirmation information is selected as the destination according to the limiting condition. If the server finds that the user query voice information does not contain the limiting condition, one of the places corresponding to the voice recognition result confirmation information is selected as a destination according to the preset rule. The preset rule may be, for example, the shortest distance.
When the corresponding place with the least queuing number is taken as a destination, the server needs to further acquire personnel queuing information of video acquisition equipment arranged at the corresponding place, and takes the place with the least queuing number as the destination according to the personnel queuing information. If the place corresponding to the voice recognition result confirmation information is a toilet, and the user inquiry voice information contains a limiting condition of minimum queuing number, the server takes the toilet with the minimum queuing number as a destination.
On the basis of the embodiment, when the voice recognition result confirms that the places corresponding to the information are multiple, the embodiment of the invention selects the destination according to the limiting conditions or the preset rules contained in the user query voice information, so that the guiding requirements of the user can be better met.
Further, based on the above embodiment, the user query voice information includes a system account name; the method for carrying out voice recognition according to the user query voice information and obtaining a voice recognition result list ordered according to the matching values through query matching comprises the following steps: and carrying out matching inquiry in a system account database according to the system account name, and carrying out descending sorting on inquiry results according to the matching degree value to obtain the voice recognition result list.
In addition to finding places, finding people is also a great need for indoor guidance. The system account name of each user is stored in the system and stored in a system account database. When a person needs to be found, the corresponding system account name can be directly spoken by voice, namely, when the user inquires that voice information comprises the system account name.
The system may preset an input entry of the user query voice information, for example, set a voice input interface button according to the location query and a voice input interface button according to the system account name query, and the received user query voice information defaults to include the location information after the voice input interface button according to the location query is clicked, and the received user query voice information defaults to include the system account name after the voice input interface button according to the system account name query is clicked. The server can conveniently know whether the user inquires the place information or the system account name included in the voice information.
If the server finds that the user query voice information comprises the system account name, the server performs matching query in the system account database according to the system account name, and the query results are descending ordered according to the matching degree value to obtain the voice recognition result list. The voice recognition result list comprises a system account name sorting list to be selected. A speech recognition result list comprising a plurality of matching results is obtained for selection by a user to avoid speech recognition errors caused by homophones, polyphones, and the like.
