It's certainly become an inconvenient name to utter around our house, due to the responses it elicits from our countertops. So my daughter came up with the idea of referring to the device as "Amelia" whenever we talk about her. It has worked brilliantly and I suggest that everyone adopt the same convention.
Can't you just change the prompt for the device to one of the other options? Though I dunno why they can't make it use any wake word you choose.
We would have liked to enable fully custom wake words, but it would have led to bad user experiences with the device either failing to wake up too often (false negatives) or having too many false positives or both.
So we compromised by enabling more than one, but not full choice.
