In order for computers to understand the human language we have to accept that is a process that has some associated challenges. It is not easy to have Computers Understand What We Say.

Each language has a syntax associated with it, being one of the biggest challenges since each language has a different syntax. Those syntaxes can be viewed as signals, and after processing and understanding the information, the computer will recognize them as actions. 

Those signals are the base of this process since the text is transformed into signals that will be applied as an action. 

It’s important to remember that each word needs to be converted to values to allow computers to process the information. The begging is to recognize the most used words because those are the most valuable and also the ones that allow understanding of the phrase.
