> your device will indicate in Keyboard Settings if your audio and transcripts are processed on your device and not sent to Apple servers

I have a reasonably recent (<2yo) MBP, which feels like it ought to be "modern enough", and in Keyboard Settings, it says "Dictation sends information like your voice input, contacts, and location to Apple to process your requests." It doesn't say anything about processing happening on my device. Yes, off-line dictation does work for me (with Wi-Fi turned off), but I'm curious under what conditions Keyboard Settings would say something about transcripts not being sent to Apple.
