I actually got Mondo working on Alexa (Amazon Echo) at our last hackathon.
The trick is going to be how do we securely do the OAuth 3 legged login. For the hackathon i hard-coded my API key into the endpoint it was hitting. I’m a huge fan of the Echo device. I’ve loaned it to another Mondo hacker for the Tesla Hackathon, but once i get it back i’m looking forward to building more things with it.
Reminds me a bit of https://www.meetcleo.com/ (which i found on this forum in the first place i think!) - that has a natural interface for engaging with the assistant (though SMS not voice). From when I trialed it, it didnt work that well though…
