Lexus RX (RX 350L, RX450h) 2016-2022 Repair Manual: Voice is not Recognized

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).
