I added a offline voice assistant program to the robot and piped in the Respeaker array, Vosk at first was rather slow, so I switched to a smaller neural network and that sped it up well. It is working quite well now. From there I added if statements on various things like 'what time is it', 'what is the current date' and so on. 

I have posted both of offline versions of the voice_assist and reading_module on a newly created github. Enjoy!
