You can now have your Alexa devices speak in a man’s voice. What this article doesn’t mention is there is also a new wakeword option - Ziggy!
I would continue to ignore the paid celebrity options though. Just a distracting, limited gimmick.
I think this new voice is the real deal, completely replacing the old female Alexa voice.
I have moved one of my Devices to Ziggy. I like it… but, there is a whole lotta fun asking Samuel L. Jackson to read you the news or tell you a joke.
Also fun, I just recently found you can have Alexa speak in accented English - including British, Australian, and Indian. (No SamJack payment required but it breaks some localized functions.)
Oh and by the way that article I linked above eventually got updated to include Ziggy. It did not originally.
I really wish Amazon would allow setting a different voice for responses without affecting the dialect it “listens” in. I loved the English UK voice for my Echo, but there were at least one or two commands I often use that didn’t work properly with it.
It’s funny, I almost think it misses more wakewords because I’m not saying them in the proper accent. 
The other limitation so far is that the male voices didn’t seem to be available in anything but US.
Alexa/Ziggy, kindly do the needful and turn off the living room lamp.
