Without doing any significant research, we can safely assume that Amazon tested multiple variations of the Amazon Echo voice to find the one that was most pleasant and accessible and understandable to the widest variety of users. Now, imagine if someone wanted to buy a device that was generally curmudgeonly, unhelpful, sarcastic, and sometimes played very loud techno music…
One YouTube creator has swapped all of Echo’s voice responses with clips from Deadmau5, and it’s frightfully hilarious.
“Alexa, what do you do?”
“Just sitting here.” 
“Alexa, what time is it?”
“Stacy, what do you want…”
“Alexa, how tall is Mt Everest?”
“Oh, I dunno.”
“Alexa, add wrapping paper to the shopping list.”
“Get out of the house.”
You get the idea.
Purchase the deadmau5 Echo wherever it’s sold! Which is nowhere.
