Practical Handson Guide for Alexa Skill Development 2022


If you intend to develop a skill, then a basic understanding of Nodejs and JavaScript.
It will be good to have an Amazon Echo device as it will help in faster testing. Otherwise you can use the web baesd Alexa Simulator.


~~ Jan 2022 Update • Start the year right! ~~There’s a new section, “TL;DR – Diving in & creating one skill”, that will help you get started with Skill Building using the latest Amazon Alexa Developer Console interface. You will build a “Zodiac Finder” skill that will help you learn several voice interaction concepts – such as Invocation Name, Intents & Slots (both Built-in & Custom), Slot Values, Interaction Model, Skill Logic, Debugging, Setting Lambda Endpoints, and using Multiple Languages. Finally, you will test the skill on the browser-based Alexa Simulator, the Alexa App and an Amazon Echo device.•••Get Meta & Practical Knowledge on Building Voice Interfaces (VUIs) / Conversational InterfacesSuitable for Beginners & Power UsersDevelopersProject ManagersMarketerCourse HighlightsGet an understanding of Lambda, Lex, Polly, S3 & moreUtilize Alexa Skills Kit v2 using Node.js 10.xBuild an Introductory Skill (for Reading out Quotes)Create an Advanced Skill using Third Party APIs (Google Maps)Get the fundamental understanding of how all pieces fit together and how a Virtual Personal Assistant works–Why this course?There is a shift happening in the way we as a species communicate with machines. With the advent of Amazon Alexa, Google Assistant, Apple Siri, and Microsoft Cortana, the focus on Voice User Interfaces or Voice Activated Conversational Interfaces is rapidly increasing.This ever changing world presents a threat to the way we operate, especially when we do not understand it. A more AI aware world might be years away, but if we learn how to talk to and control the machines then we grow collectively.–The “Real” Goal for this courseYes, Amazon Alexa and similar voice activated interfaces look and sound pretty cool. You can use the extensive documentation available with each interface to build out the skills.However, just learning the syntax of a particular system is not enough. To mature as an individual, you need to gain the foundational skills on how these interfaces operate, and be technology agnostic when it comes to building these conversational interfaces.The real goal of this course is to get you competent enough to understand the complexities that go behind designing and creating the voice user interfaces, so that you can immediately assess how different pieces of the puzzle fit together.–Practical Implementation of the Real GoalNo matter how much of the fundamental knowledge you have, if you are unable to put it to practice, then usually it is of no real value.This course not only focuses on getting you ahead of others in understanding how a voice user interface works, but helps you build your very own uber cool personal assistant using Amazon Alexa, that can do what you can make it do.Building a personal assistant using Alexa Custom Skills is just one of the techniques, and you will learn very soon that you can design a variety of interfaces through the knowledge that you gain.Amazon has always been ahead of the game in terms of building voice interfaces, and you will be able to understand how you can leverage what Amazon has to offer to get you to communicate with machines effectively.–What will you learn?By using Amazon Alexa, and building a Voice Activated Personal Assistant, you will gain the following:Understand what is Amazon Alexa and its ecosystemWhat are Voice Interaction Models, and how they can help you build a better and reliable voice interfaceKnow the technologies that work behind a voice activated interfaceUse Amazon Services such as Lambda, S3, CloudWatch, & IAM and how they interact with each otherDeconstruct an Alexa Skill, and get clarity on what are Intents, Slots, and UtterancesDevelop with Node.js 10.x and Alexa Skills Kit SDK v2 to build a personal assistant that responds to your queriesConnect with Third Party APIs and process information, use asynchronous requests, promises, and await expressions in async functionsMaintain data persistence within an Active Alexa SessionIntroduce errors, and Test Alexa Skills through 4 different modes including simulators and physical devicesLeverage the Amazon Web Services to build a Consistently Reliable ArchitectureYou will get a complete checklist on what all you will be achieving, with code that is available on GitHub for easy access. The lectures will have links, files, and diagrams attached to them wherever relevant.

Even if you do not have the knowledge of Node.js, you will be able to fundamentally understand how you can build custom skills, and implement it in your own preferred language.The sooner you get into building the voice interfaces, the faster you will be able to mould the machines to your liking.
