Jarvis

An off-grid voice assistant.

Currently a work-in-progress (aren't they all?), based on the Mycroft open voice assistant and currently crammed into a cute, old-fashione speakerphone.

As is, it is much more privacy-oriented than things like Amazon Alexa and Google...whatever they call it, but it still relies on "the cloud" for a few things. The goal of this project is to address that to allow for completely offline use.

There are a number of projects that have laid the groundwork for this, and Mycroft themselves are working on it too, but so far I haven't found a complete "turnkey" package to do it, so I'm giving it a shot.

TODO

• Setup basic functional Mycroft installation
• Cram this into a cool case
• Do a better job of cramming and connect as many of the physical controls as is reasonable
• Produce some basic documentation of what's been done so far
• Start reducing dependence on "the cloud"
  • STT
    • Setup Mozilla DeepSpeech
    • Test pointing Jarvis at the local DeepSpeech server
  • API
    • Test OVOS Local Backend

Detailed (if poorly-written) progress information can be found in the journal.
