Lexus RX (RX 350L, RX450h) 2016-2025 Repair Manual: Does not Recognize Voice Commands Performed to Contact Support Center

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. (Example: When "Find a gas station in New York" is spoken, "Find a gas station in New York" is displayed in the voice recognition result display area.)
• 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).
