AI for Noobs: How Amazon Alexa Works

Too Long; Didn't Read

Alexa is a voice-based, AI-powered digital assistant, Alexa can reply to simple questions, perform various tasks and commands. In this article, we are going to look at how Alexa works. It works by processing requests or commands like -*Alexa Put on the lights*- through a machine learning technique called Natural Language Processing, NLP. NLP is simply the manipulation of forms of natural language like text, audio, speech using algorithms. Alexa performs the same process explained above to return a response back to you but in reverse, Alexa just goes through her database, finds the best words to describe the answer to your questions, and then outputs that response in speech form.
