Abstract: An artificial intelligence device mounted on a vehicle is provided. A sensing unit acquires a gyroscope sensor value, an acceleration sensor value, a GPS sensor value, and a proximity sensor value. If the acquired data satisfies a predetermined reference value, a processor inputs the acquired sensor values to an artificial intelligence model, acquires whether an impact requiring self-diagnosis occurs and impact direction information as a result value, selects an ECU module to perform self-diagnosis according to the acquired result value, and performs self-diagnosis.

Abstract: Provided is an artificial intelligence (AI) apparatus for managing an operation of an artificial intelligence (AI) system. The AI apparatus includes: a communication unit that receives state information from at least one member AI apparatus included in the AI system, respectively; a memory that stores apparatus information on the at least one member AI apparatus, respectively; and a processor that: upon acquiring a control command of a user, determines a target member AI apparatus to perform the control command; determines whether the target member AI apparatus is capable of performing the control command or not; transmits the control command to the target member AI apparatus if the target member AI apparatus is capable of performing the control command, and outputs a response indicating that the target member AI apparatus is not capable of performing the control command if the target member AI apparatus is not capable of performing the control command.

Abstract: An artificial intelligence apparatus for recognizing speech by correcting misrecognized word includes a microphone and a processor. The processor is configured to obtain, via the microphone, speech data including speech of a user, convert the speech data into text by using an acoustic model and a language model, determine whether an uncertain recognition exists in an acoustic recognition result according to the acoustic model, determine whether the converted text is a normal sentence by using a natural language processing model if an uncertain recognition exists in the acoustic recognition result, determine a sentence most similar to the converted text among sentences pre-learned by using the language model if the converted text is not a normal sentence, replace the converted text with the determined most similar sentence, and generate a speech recognition result corresponding to the speech data by using the converted text.
