Personally I'm looking forward to the potential of complete customisation over my voice assistant. I would like to be able to add custom pre recorded wave file confirmations when a task is done. Or pre-recorded wake up responses. For instance I'd like to have some sound effects from the Jarvis ai in iron man say things like "certainly sir" after completing a request. Or if it was an alarm that I requested "the alarm is set". What about you guys and gals?
I've been using Google home minis for voice control. Apart from getting away from Google, I'd like to see some modding to use their mics and speakers. I've liked using them as a Chromecast device from squeezelite, but I think that could even be possible with esp.
