Flip it around and it works too. Anyone who wants to could potentially set all of the text-to-speech systems they use (their phone/house's voice interaction, listening to audiobooks, warning messages from their car/plane, etc.) to whichever voice profile they like best. Basically what TTS has been trying to do since the 70s or 80s, but with an infinite number of natural-sounding voices.
Maybe pick a couple of different ones for context-aware messages. Something familiar/reassuring for most messages, something less comfortable for "terrain!"-type alerts. If the model supports it, it could even morph between the two as the criticality of the message escalates.
