Creating your own Alexa skill might seem daunting, but it’s surprisingly straightforward. This guide provides a step-by-step walkthrough of the process, inspired by a personal journey to build a simple rugby fact skill. Whether you’re aiming for a free hoodie or diving into voice app development, this guide will equip you with the basics of How To Build Alexa Skills.
Setting Up Your Alexa Skill: The Foundation
The first step in learning how to build Alexa skills involves setting up your skill in the Amazon Developer Portal. Signing up for a free Amazon Developer account is a prerequisite. The developer console is user-friendly, and creating a skill is as simple as following the on-screen prompts. Crucially, you’ll need to choose an Invocation Name – the name users will use to activate your skill. For simplicity, using the skill’s name is a good starting point.

Next, define the Interaction Model using the Skill Builder. Similar to Microsoft’s luis.ai, you’ll create Intents and add sample utterances (phrases users might say) to trigger those Intents.

Once done, save and build your model. Build times are generally short.
AWS Lambda Function: Bringing Your Skill to Life
A key component in how to build Alexa skills is understanding AWS Lambda. This serverless compute service allows you to run code without provisioning or managing servers. While experience with AWS is helpful, setting up a Lambda function for your skill is relatively easy. Choose the Alexa Skills Kit blueprint, use the Alexa Skills Kit as a trigger, and configure a Lambda role. Remember, you might need to set up the trigger after creating the function.
Connecting the Dots: Voice User Interface and Lambda Function
This step involves connecting your Voice User Interface (VUI) to your Lambda function. This essentially means linking the front-end of your skill (how users interact with it) to the back-end logic (what happens when they do). This is primarily a matter of filling out a form within the developer console. For basic skills, this step is uncomplicated.

Testing Your Alexa Skill: Ensuring Functionality
Thorough testing is crucial in how to build Alexa skills that work flawlessly. Amazon provides tools to test both the voice and service simulators within the developer console. Additionally, you can create test events within AWS Lambda. Services like Echosim.io provide further testing capabilities.
Customization: Making Your Skill Unique
This is where your creativity comes into play. Customize the provided template with your own content. For a fact skill, this involves replacing the placeholder facts with your own. This step also includes customizing responses, help messages, and other aspects of the skill’s personality.
Certification and Publication: Sharing Your Skill with the World
The final steps in learning how to build Alexa skills involve preparing your skill for publication. This includes providing a skill description, example phrases, icons, and answering privacy questions. After submitting your skill for certification, Amazon typically provides feedback within seven days.
Conclusion: Empowering You to Build Alexa Skills
Building an Alexa skill is a rewarding experience. This guide demystifies the process, providing a clear roadmap for creating your first voice app. By following these steps, you can unlock the potential of the Alexa Skills Kit and contribute to the growing world of voice-activated technology.
