You can also run Alexa from your desktop and integrate Alexa to any other physical device besides the Echo with the Alexa Voice Service. Great for those who want to play with Alexa, but don't want to shell out money for an Echo. Amazon has an easy to follow reference implementation for this. https://developer.amazon.com/public/solutions/alexa/alexa-vo...

great, been looking for ways to use Alexa outside Echo (which isn't out in the UK).

I've got a couple of old android phones lying about which I'd like to use as DIY Echos - is there a way to get it working with "OK Alexa" rather than a mouseclick?
