Special thanks to Fernando Coto (Zepto Segundo) for the podcast materials and Rocky Ace Turbeaux for the cigars.

Fernando Coto comes from the Graphic Design background and started as a Web Designer back in 2001. He trained himself to become what we know today as a UI/UX specialist and has followed the development and evolution of this field since its early days. Fernando has worked as a UI Designer since 2007 mostly for the Banking and Finance industries. He decided to participate in this project in order to evaluate the impact of voice interfaces and what he expects will be a transformation from User Interface Design to Human Interaction Design, involving visuals, voice, and gestures.

Today the voice technology is being integrated into many mobile devices such as iOS Siri, Android Google Assistant and Windows Phone Cortana allowing you to perform mobile phone tasks using the voice commands. The voice technology is even coming into our home through Amazon Echo and Google Home allowing you to control home appliances like bedroom lights or opening the garage door. Also you can use your voice in your car allowing you to perform hands free tasks like making a call, texting and playing a music.

This book is designed to help you understand and create voice user interfaces for Google Assistant, Google Home, Android Auto and Amazon Echo. It will help you understand the natural language processing platforms like Alexa and Dialogflow and create Node.js middle tier REST API that will fulfill the platforms' requests. Furthermore, you will take advantage of the cloud technology to deliver your infrastructure back-end needs in order to help deliver your application faster and reliably.
