" summary

Compares Amazon Alexa, Google Assistant and Mycroft by building prototypes on Raspberry Pi and Orange Pi Zero and reporting what actually works: Alexa SDK (C++), open on GitHub with ~69 commits runs on Raspbian after compiling but commercial devices require Amazon certification; Google Assistant SDK (Python), supports ARMv7 and x86_64 works with Google Voice Kit and Orange Pi and needs the Google Home app and cloud access; Mycroft core (~3,000 commits) uses Precise wake-word and defaults to cloud STT (DeepSpeech available) so it’s open but currently still dependent on Internet. All demos function; offline STT remains the blocker.
