Take for instance the NYC subway system. The female voice announces the stop the train has just arrived at, while the male voice instructs customers to 'stand clear of the closing doors' and to 'be aware of pickpockets, take care to ensure the safety of your personal property.'
This is quite intentional. We simply react better when certain types of voices are used to convey certain things.

I am not saying that Toni's contributions are negligible, rather that her and her team are part of a bigger organization that built and improves Alexa.

However, it concerns me that every major player out there tries to create a locked playing field with their devices ("amazon home" vs "google home").
I really don't like the idea of buying home automation devices that are meant for one specific solution. Moreover, I also fear that I could become dependent on a corporate-owned device/service, with no direct alternatives (or with convoluted migration paths).
And that's not even mentioning the privacy issues, or (ok, I touched that a bit) the freedom to hack a bit the API (what if I would like to add a completely custom command, change the detection keyword, etc...)
There are some open solutions such as Mycroft, but I must confess I haven't looked much at it. I won't consider this technology mature or ready for use until those concerns are addressed, which could take some time: it also seems to me that those "personal assistants" are more suited to a central architecture (which raises the question: did this architecture influence their design, or is it the only possible solution for a reliable "personal assistant"?).
Even though I have iPhone and many HomeKit enabled devices, the fact that Wink and Alexa support so many integrations keeps me from even attempting to buy into a very locked in ecosystem like Apple or Google are attempting.
Finally, in the absence of a pre-existing integration, you can always write your own, which can't really be said for any of the other major players that aren't completely roll your own.
I've been pleasantly surprised by the flexibility the Alexa platform has shown, and it's becoming increasingly part of our home workflow because of how well it plays with other things.
