You guys may have seen Alexa running on the RPi 2 the past few months. I started seeing the news show up on my Google news feed and wanted to try on the BeagleBone. Overall I think it works pretty well on the little AM335x I think with some optimizations it could be a bit better, but very usable.
My python project is over on github (https://github.com/merdahl/AlexaBeagleBone), a fork of the AlexaPi project. The only Pi-specific code was the GPIO module, but I also wanted to improve the audio streaming support of the AlexaPi project, as this was my main intended use.
If you’re interested in building your own Alexa BeagleBone, and have not setup an Amazon Developer account before, Youtube user Novatech Spirit has a good walk-through setting up your Amazon developer account and a sample Alexa project: https://www.youtube.com/watch?v=frH9HaQTFL8
