There are three core technologies that power Alexa. It’s not just Alexa, either. All voice assistants such as Siri, Google Home, etc. use these important technologies. They are Automatic Speech Recognition (ASR), Natural Language Understanding (NLU), and Text To Speech (TTS).
For my dad’s birthday, I was wondering what I should give him. I briefly considered buying him a store-bought present, but I didn’t know what I should get. There wasn’t anything that seemed good enough. Then, I thought of the best thing he had done for me this year. My mind immediately went to one thing: Alexa.
