s2-2, the background voice skill arbitration module firstly distributes the voice instruction to the background voice skill analysis module, the background voice skill analysis module searches for the voice skill corresponding to the background, and returns the recognition result to the background voice skill arbitration module;
s2-3, if the returned result can be identified as background voice skill, the background voice skill arbitration module calls a background voice skill download management module to obtain 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 the background voice skill response module; if the skill does not belong to the downloaded voice skill, sending the identified one or more voice skill information to the recommended voice skill generation module; if the returned result does not hit the background voice skill, the background voice skill arbitration module sends a recognition failure message to the background voice skill response module;
s2-4, if the downloaded voice skill or the missed background voice skill is recognized in the last step, the background voice skill response module returns the skill recognition result to the vehicle-end voice skill response module for execution; if the downloaded voice skill is not recognized in the last step but other background voice skills are hit, the recommended voice skill generation module converts the recognized voice skill into a recommended voice skill list and sends the recommended voice skill list to the background voice skill response module;
and S2-5, the background voice skill response module sends the pushed voice skill list to the vehicle-end voice skill real-time recommendation module.
9. The vehicle-mounted voice skill real-time recommendation downloading method according to claim 8, wherein the step S3 specifically includes:
s3-1, the vehicle end voice skill real-time recommendation module is used for inquiring whether the user needs to download new skills in real time, and if the user chooses not to download, the process is ended; if the downloading recommendation skill is selected, the voice skill real-time recommendation module calls a voice skill downloading module to respond to a voice skill downloading request of a user and update a downloaded voice skill mapping table, and sends the mapping table to a vehicle-end voice skill downloading management module;
and S3-2, updating and storing the downloaded voice skill mapping table by the vehicle-end voice skill downloading management module, prompting a user to finish downloading, synchronizing the latest voice skill mapping table to the cloud background voice skill downloading management module, and ending the process.
10. The vehicle-mounted voice skill real-time recommendation downloading method according to claim 8, wherein the step S2-3 further comprises:
and if the voice skill identified by the background voice skill arbitration module belongs to the downloaded voice skill and a plurality of identification results exist, sending the voice skill analysis result with the highest identification credibility to the background voice skill response module.
