I'm starting to look into the MycroftAI. It sounds like with this release I could use Mycroft+DeepSpeech on a new RaspberryPi for a completely offline smart speaker, do I understand that right?
Correct. The latest release with the TensorFlow Lite model runs in real time on a Raspberry Pi 4. I'm not sure if the Mycroft integration is updated to the latest version though, as it was just released.
