Description

Server, device and method for providing voice recognition service The present invention relates to a server, a terminal, and a method for providing a voice recognition service. PC web browsers include an update function that allows you to update web pages. Through this function, you can set the default cache retention period and configure the criteria for updating web pages. Since AI terminals do not differ from web browsers in their basic internet connection methods, their caching policies are also similar. If data stored in the cache is not updated on an AI terminal, not only is it impossible to determine whether the currently used cache contains the latest data, but it can also affect network traffic. Meanwhile, when examining voice commands received from users or text, audio, and image data provided to users during the process of providing AI services through AI terminals, there are many instances where the same requests are received from users. Artificial intelligence servers providing AI services utilize caching to reduce processing time for user requests or increase system processing capacity. They store data and result data for voice commands entered by users in the cache, and when a request for the same voice command is received from a user, they provide the cached result data to the user through the AI terminal. However, if the AI server intends to provide result data for voice commands requested by multiple AI terminals to multiple AI terminals, a problem arises in which network traffic between the AI server and the multiple AI terminals increases, leading to an increase in the load on the AI server. Meanwhile, using a cache on the AI terminal eliminates the need to receive binary data from the AI server, thereby reducing network traffic between the AI terminal and the AI server, decreasing the network traffic capacity of the AI server, and lowering the load. However, since the AI terminal cannot provide new versions of binary data using only the binary data stored in the cache, the cache must be updated.
