Electronic device and method for providing artificial intelligence services based on pre-gathered conversations

A method of operation for an electronic device capable of providing a recommendation service related to an intention of a user in response to a wake-up utterance invoking a voice-based intelligent assistant service, the method comprising:

• collecting voice data of a user based on a specified condition prior to receiving the wake-up utterance;
• transmitting the collected voice data to an external server and requesting the external server to construct a prediction database configured to predict the intention of the user;
• determining, upon receiving the wake-up utterance, a weight based on at least one piece of information stored in the prediction database;
• and
• determining a recommendation service related to the intention of the user based on a weight and outputting the determined recommendation service.

A method of operation for a server to provide a recommendation service related to an intention of a user in response to a wake-up utterance invoking a voice-based intelligent assistant service, the method comprising:

• receiving voice data from an electronic device;
• analyzing the context of a user's conversation included in the voice data;
• determining whether the voice data is sufficient to identify the user's intention based on the analyzed context;
• generating a path rule based on the voice data being sufficient to identify the user's intention, and cumulatively storing the voice data based on the voice data not being sufficient to identify the user's intention;
• constructing, based on the path rule being generated, a prediction database using the generated path rule to predict the user's intention;
• and
• transmitting, based on the electronic device receiving the wake-up utterance, at least one path rule included in the prediction database to the electronic device.
