Voice Commands
WARNING: This page is about a different car, the 2018 Lincoln Navigator. However, it is still accessible from the selected car via links, so may be relevant.
When the steering wheel voice button is pressed, the SCCM sends a message to the APIM over the CAN indicating the request to initiate voice commands.
When voice commands are spoken, the monitored sounds are converted into analog signals by the microphone and sent to the APIM. The APIM software interprets them and outputs a command.
