s2-3, if the returned result can be identified as background voice skill, the background voice skill arbitration module calls a background voice skill downloading management module to acquire the downloaded voice skill configuration of the user or the equipment, and if the identified voice skill belongs to the downloaded voice skill, the voice skill analysis result is directly sent to a background voice skill response module; if the voice skill information does not belong to the downloaded voice skill, sending the identified one or more voice skill information to a recommended voice skill generating module; if the returned result does not hit the background voice skill, the background voice skill arbitration module sends an identification failure message to the background voice skill response module;
s2-4, if the downloaded voice skill is recognized in the previous step or the background voice skill is missed, the background voice skill response module returns a skill recognition result to the vehicle-mounted voice skill response module for execution; if the voice skills are not downloaded but other background voice skills are hit in the previous step, the recommended voice skill generating module converts the recognized voice skills into a recommended voice skill list and sends the recommended voice skill list to the background voice skill responding module;
s2-5, the background voice skill response module sends the pushed voice skill list to a voice skill real-time recommendation module at the vehicle machine side.
9. The method for downloading real-time recommendation of vehicle-mounted voice skills according to claim 8, wherein the step S3 specifically comprises:
s3-1, a vehicle-mounted voice skill real-time recommending module is used for inquiring whether a user needs to download new skills in real time, and if the user selects not to download, the process is ended; if the downloading recommended skills are selected, the voice skill real-time recommending module calls the voice skill downloading module to respond to the user downloading voice skill request and update the downloaded voice skill mapping table, and sends the mapping table to the vehicle-mounted voice skill downloading management module;
s3-2, the vehicle-mounted voice skill downloading management module updates and stores the downloaded voice skill mapping table, prompts a user to complete downloading, and synchronously synchronizes the latest voice skill mapping table to the background voice skill downloading management module at the cloud end, so that the process is finished.
10. The method for downloading real-time recommendation of vehicle-mounted voice skills according to claim 8, wherein the step S2-3 further comprises:
if the voice skills identified by the background voice skill arbitration module belong to downloaded voice skills and a plurality of identification results exist, sending a voice skill analysis result with highest identification reliability to the background voice skill response module.
