Causal Thought Idea

Take here as the causal thought input.

I want to build a voice assistant at the first time.

Thus: I say some words to a module has the ability to record my words. Words about my work. Then it can attach to the main board and transmit all my words there.

Then the main board can detect my words and know how to store my work. Display it well.

But I found I should know the principle of recording, processing and others. I then decide starting with the easy one, by typing words into the modules to relize my work.
