Yesterday, I shared the design plan for the smart assistant 'JARVIS'. I wonder what everyone thinks after reading it? If this plan were actually implemented, what would the effect be?
Today, I am excited to present the project showcase, let's see how to create our own smart voice assistant!
Phase two project report has been uploaded to the electronic forest:
