## Description
* Written mostly in Python
* Work in progress
❗ New versions of the voice assistant will not work on Raspberry Pi due to missing CPU instruction sets needed by some AI scripts. If you are looking to play along with the old version on your Raspberry Pi, check the [raspberry branch](https://github.com/nerdaxic/glados-voice-assistant/tree/raspberry).
