Voice is not Recognized [06/2018 - 09/2022]: Procedure

  1. CHECK CONDITION 
    1. While paying attention to the condition of the spoken voice command, perform a voice recognition operation.

      OK

      Voice command is recognized normally.

      HINT: 

      • When the voice command is recognized, the content of the voice command is displayed in the voice recognition result display area to the right of the mic icon.
      • If an unnecessary word (such as "um" or "ah") is spoken before or after the recognition word, the system incorrectly recognizes the recognition word.
      • The system cannot recognize voice commands when multiple people are speaking simultaneously.
      • If the speaking speed is too fast or too slow, the recognition rate may decrease.
      • The system may have difficulty recognizing voice commands depending on the voice quality (such as a hoarse voice due to poor physical condition).
