  • Publication number: 20220343900
    Abstract: An image display device and a voice recognition method thereof are proposed. The image display device and voice recognition method thereof stores received first utterance data in a first buffer when a wake up word is recognized from utterance data, stores second utterance data consecutively uttered from a user in a second buffer, stores third utterance data consecutively uttered from the user in a third buffer when verification of the wake up word is successful on the basis of the first utterance data after booting of an operating system is completed, and joins the second uttered data and the third uttered data respectively stored in the second buffer and the third buffer, so as to perform voice recognition for the utterance data consecutively uttered by the user. Accordingly, including the commands uttered at intervals after the wake up word, user's commands that are consecutively uttered may be recognized.
