Yeah it's a clone of the trivial parts of the Echo, but not the difficult parts that are necessary to make it great, specifically: * Beamforming microphone array (this is a real clone: http://www.xmos.com/products/microphones ) * Wake-word / hot-word detection ("Ok Google", "Alexa", etc.) * Intent recognition / NLU
wow, that microphone array you linked costs USD$750! Are there any cheaper alternatives?
The high price is because it's a development board. (I think it's a silly to price development boards highly, but it is very common.)
