According to a report from Windows Central, Microsoft is contemplating to add support for digital assistants you can chat with on your Xbox One.
That brings up the question of why someone would use a voice assistant on their Xbox One when they might already have an echo or mobile phone with google assistant, siri or bixby.
Exactly this.
Besides, I can’t really see MS prioritizing Alexa over Cortana. If anything, their continuing push to single architecture suggests to me that Cortana integration into XBox and synchronization with your MS account across all your devices is where it’ll get to.
