Abstract: An AI device is provided. The AI device includes a content output interface to output video data contained in content and voice data contained in the content, and a processor to control the content output interface to acquire a voice recognition result by providing, to a voice recognition model, content extraction information including at least one of video information acquired from the video data in the content or tag information of the content and the voice data, and control the content output interface to output the voice recognition result.

Abstract: Provided is an artificial intelligence (AI) device for recognizing speech of user. The AI apparatus includes: a microphone; and a processor configured to: receive, via the microphone, a sound signal corresponding to speech of the user, recognize the speech from the sound signal using a language model, determine an intention of the user based on the recognition result, determine whether the determination of the intention is successful, obtain a user's application usage log if the determination of the intention is not successful, and update the language model using the obtained user's application usage log.

Abstract: An artificial intelligence apparatus for recognizing speech of a user includes a microphone, and a processor configured to receive, via the microphone, a sound signal corresponding to the speech of the user, acquire personalize identification information corresponding to the speech, recognize the speech from the sound signal using a global language model, calculate a reliability for the recognition, and if the calculated reliability exceeds a predetermined first reference value, update a personalized language model corresponding to the personalize identification information using the recognition result.
