Yea, here are the steps involved. If something goes sideways on any of the steps Alexa will give you those types of "I don't know" type of replies.....So when I make a request/command, it sends the request to the (I’m guessing) Amazon Web Service Clouds / AI unit (or whatever they call it) to process and sends back the commands back to the car to execute…
hmm… I always assumed that the processing chip within the vehicle computer took care of (most of the regular, often-used) commands internally…
A lot more to learn.
When a user asks Alexa a question or gives a command using their voice, the device records the voice and sends it to Amazon's Alexa Voice Service (AVS) over the internet. AVS then uses Automatic Speech Recognition (ASR) and Natural Language Understanding (NLU) to parse the recording into commands it can understand and identify the user's intent. AVS then processes the response and may make a request to a third-party server (it does this where Lucid commands are involved) if needed. Finally, AVS sends the relevant output back to the device.
