Lexus RX (RX 350L, RX450h) 2016-2026 Repair Manual: Voice is not Recognized

PROCEDURE

1.

CHECK CONDITION

(a) 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.*1
  • When the voice recognition prompt function is set to "On" and a voice command is recognized normally, the same voice command is repeated by the voice guidance function.*2
  • 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).
    • *1: w/ Voice Recognition Result Display Function
    • *2: w/o Voice Recognition Result Display Function
OK

END (VOICE RECOGNITION MAY BE DIFFICULT DUE TO SPEECH CONDITION)
