Getting Started
To create a custom Alexa skill, you'll need to get started with the basics. You can create just about any skill you can imagine, from simple call-and-answer prompts to elaborate quiz games.
To get started, you'll need to know what you need to know about creating Alexa skills. The skill service can be either a user-implemented web service or the AWS service, which is configured in the "Endpoints".
Here's a quick rundown of what you need to do to get started with the AWS service:
- Click the “Endpoints” tab.
- Select the “AWS Lambda function”.
You'll also need to copy the skill ID, located in the "Endpoints", by clicking "Copy to Clipboard".

To start, you'll need to enter the name of your Lambda function, which must be unique. Use "HelloWorld" for now.
This name needs to be unique, and it's a good idea to choose something that will help you remember what your function does.
Make sure the region is set to "US-East (N. Virginia)" in the top right corner. If it's not, select it from the dropdown menu.
The Alexa Skills Kit is only hosted in East US (N. Virginia) at the time of this writing, so this is the correct region to choose.
You'll need to scroll down to the "Lambda function code" section and paste the code you copied from GitHub into the large text box.
This code is the foundation of your function, and it's essential to get it right.
In the "Lambda function handler and role" section, set the role to "lambda_basic_execution".

Naming and Sharing
Naming your skill is a crucial step in the process, and it's best to choose a name that Alexa can easily understand. Picking a name that's too complex can lead to Alexa having trouble recognizing it.
You should keep Alexa's limitations in mind, such as its difficulty with recognizing first and last names. For example, if you're creating a family quiz game, it's better to name it something like "The Family Fun Quiz" instead of "The Alexander Family's Quiz."
When sharing your skill, you can share it via email, Facebook, Twitter, or Pinterest, or get a link to share. To do so, go to Skills You've Made > Details > Share With Others.
Name Your

Naming your skill is a crucial step, and it's best to keep Alexa's limitations in mind.
Picking a name that's too complex, like "The Alexander Family's Quiz", can be a problem if Alexa can't recognize first and last names.
Alexa has trouble with certain words, like "our", so it's best to avoid those when choosing a name.
You can simplify your name by choosing a more straightforward title, like "The Family Fun Quiz."
Share Your
You can share your skill with others through various channels, including email, Facebook, Twitter, or Pinterest. To get a link to share, go to Skills You've Made > Details > Share With Others.
Sharing your skill is a great way to get feedback from friends and family. You can even publish your skill to the Alexa Skills Store, making it available for Alexa users in the U.S. to find and use.
To publish your skill, you'll need to go through a review process. Here's the step-by-step process:
- Go to Skills You've Made and click on the skill you want to publish.
- Click on Publish to Skills Store (if you've shared your skill, you'll need to revoke sharing).
- Enter your Alexa Skills Store name, which will help customers find you in the store.
- Choose a category for your skill and add relevant keywords to help people find it.
- Add a short description and detailed description of your skill.
- Fill out the policy details about your skill and its intended audience.
- Review the information and submit your skill for review by Amazon.
Once you've submitted your skill, you'll need to wait for an email notification about whether it's been approved or rejected.
Introduction and Setup
To create an Alexa skill, you'll need to start with the basics. Out of the box, a user can give Alexa a number of voice commands, but these tasks are called "Alexa Skills" and can be expanded upon.
Developers can build new custom skills using the Alexa Skill Kit (ASK), a collection of APIs and tools that handles the hard work related to voice interfaces. ASK helps developers build skills quickly and easily.
To get started, you'll want to set up your code locally, which can be done by clicking the "Code" tab on the Alexa Developer Console dashboard.
Introduction to
Alexa Skills are voice-driven apps that perform tasks upon user request. Out of the box, users can give Alexa voice commands to create a to-do-list, set an alarm, play a song, or get the news.
Developers can build custom Alexa Skills using the Alexa Skill Kit (ASK), a collection of APIs and tools that handle voice interfaces. ASK makes it easy to build skills quickly and easily.
Alexa has a number of built-in skills, but developers can create new ones. With ASK, developers can build a skill in no time.
You can turn your own idea for a custom voice command into a working Amazon Alexa skill.
Set Up Locally

To set up your Alexa Skill locally, you'll need to use a local editor, which is even cooler than coding on the browser. This will help you build the Alexa Skill on your computer.
First, install and configure the Amazon Skills Kit Command Line Interface (ASK CLI). This will give you access to offline tools that will make your life easier.
Next, go back to the web editor and click on Offline Tools. Copy the command line and paste it into your command prompt. This will initialize the Alexa Skill locally on your computer, and you'll have the Lambda folder with a NodeJS package.
Now, you can install dependencies and setup scripts as you would in any other project. This is a big step forward, and you'll be glad you took the time to set up your Skill locally.
Ingredients and Building
To create an Alexa skill, you'll need an Amazon Developers Services (ADS) account. It's free and easy to create one, so don't hesitate to sign up now.
You'll use the Alexa developer console to build your skill, starting with the "Create Skill" button. This will guide you through the process of choosing a skill name, languages, and hosting options.
Ingredients for Building

To build a custom Alexa skill, you'll need an Amazon Developers Services (ADS) account. It's free and easy to create one.
You'll use the Alexa developer console to build your skill, where you can choose a Skill name and select the language(s) it will support. For example, you can choose to support multiple languages.
You'll also need to select a model and hosting option, and we suggest using a custom model to build an Alexa-hosted Skill. This will give you more flexibility and control over your skill's functionality.
Here's a brief overview of the hosting options:
Ultimately, the choice of hosting option will depend on your specific needs and requirements.
Build Custom Feature
To build a custom feature, you need to start with a clear idea of what you want to create. For example, our custom Alexa skill, "My Favorite Chess Player", aims to provide a list of chess players and offer a short biography upon request.

The first step is to click the "Alexa Skills Kit" and then the "Create Skill" button to open the "Create a new skill" form.
To create the skill, you need to enter the name "My Favorite Chess Player" in the "Skill name field" and select "Custom". This will allow you to tailor the skill to your specific needs.
The skill will handle three main request types: About, which will provide information on the user's request for help.
To build the custom feature, you'll need to follow these steps:
- Click the "Alexa Skills Kit"
- Click the "Create Skill" button
- Enter "My Favorite Chess Player" in the "Skill name field", and select "Custom"
By following these steps, you'll be able to create a custom feature that meets your specific needs and goals.
Interaction Model
The interaction model is the backbone of your Alexa skill, allowing users to interact with your skill through voice commands. It's made up of intents, which are actions that fulfill the user's requests.
An intent has at least one utterance, a predefined word, phrase, or sentence that the user might say to invoke the intent. For example, if you're building a skill for ordering food, an intent might be "order pizza." This intent would have a corresponding utterance, such as "I'd like to order a pizza."
The skill interface processes the user's speech requests and maps them to intents within the interaction model. If a specific intent is detected, the skill interface creates a JSON encoded event, which is passed to the skill service.
Communication Within the Custom
Communication within a custom Alexa skill is a two-way process between the skill interface and the skill service. The skill interface processes user speech requests and maps them to intents within the interaction model.
The skill interface creates a JSON encoded event from the user's request, which is then passed to the skill service. The skill service determines what actions to take in response to this event and returns a JSON encoded response to the skill interface.
The skill interface processes this response and sends the speech response back to the user through the Echo. This process happens seamlessly, allowing users to interact with the skill without any issues.
The skill interface and skill service work together to provide a smooth user experience. Here are the key components involved in this process:
- Click the “Start a Skill” button.
- Click the “plus” sign to add the skill.
In the case of our custom skill, "My Favorite Chess Player", the skill interface and skill service work together to provide a list of chess players and ask the user if they want to hear more about any of them. If the user agrees, the skill will read a short biography corresponding to the chosen player.
Part 1: Building the Interaction Model
Building the interaction model is a crucial step in creating a custom Alexa skill. You'll need an Amazon Developers Services (ADS) account to implement the skill interface within the Amazon Alexa developers platform.
The skill interface processes user speech requests and maps them to intents within the interaction model. Every intent has at least one utterance, a predefined word, phrase, or sentence that the user might say to invoke the intent.
To get started, you need to create an ADS account if you don't already have one. It's easy and free.
The interaction model is built by defining the intents and their corresponding utterances. This is done within the Amazon Alexa developers platform.
Here's a quick overview of the key components involved in building the interaction model:
- Intents: actions that fulfill the spoken requests from the user
- Utterances: predefined words, phrases, or sentences that invoke an intent
By defining these components, you'll be able to create a robust interaction model that accurately interprets user requests and provides the desired responses.
Endpoints and Testing
To configure the skill service, you'll need to choose the AWS service in the "Endpoints" tab and select the "AWS Lambda function". This will allow your skill interface to communicate with the Lambda function.

The skill ID is located in the "Endpoints" and needs to be passed to the Lambda function. You can copy it by clicking "Copy to Clipboard". This ID is essential for connecting your skill interface with the Lambda function.
To test your custom Alexa skill, you can use an Alexa device, the Echo Simulator Community Edition at Echoism.io, or the service simulator under the Test tab. The service simulator displays the JSON input and output, allowing you to see the communication between the skill interface and the Lambda function.
Here are the different types of requests sent to the Lambda function:
- LaunchRequest: sent when the user invokes the skill by saying its invocation name
- IntentRequest: sent when the user interacts with the skill, with the intent inscribed in the event
- SessionEndedRequest: sent when the session ends due to an error, user says "exit", or user doesn't respond
Choosing Endpoints
Choosing Endpoints is a crucial step in setting up your custom Amazon Alexa Skill. To choose the AWS service, click the "Endpoints" tab and select the "AWS Lambda function".
You'll need to pass the skill ID to the Lambda function, which is located in the "Endpoints". To do this, click "Copy to Clipboard" to copy the skill ID.

The skill interface sends three types of requests to the Lambda function: LaunchRequest, IntentRequest, and SessionEndedRequest. These requests are encoded in JSON format by the skill interface in accordance with the interaction model.
The responses sent by the AWS service to the skill interface are also encoded in JSON format. For our simple custom skill, we'll configure the Lambda function using Python, which is supported on the AWS services.
Here's a summary of the events and responses:
To create a Lambda function, click the "Create function" button, located in the lower-right corner of the "Create function" form. Then, select the "Alexa Skills Kit" in the "Add triggers" list.
Testing the
Testing the Alexa Skill is a crucial step in the development process. You can test it using the service simulator under the Test tab, which allows you to write what you want to say in the empty field or hold the microphone and speak.

To test the skill in the service simulator, you'll need to click the "Test" tab, toggle the Test button on, and then write or speak your request. This will display the JSON input and JSON output on your screen.
The service simulator is a great tool for testing, as it shows you the exact JSON input and output that the skill is sending and receiving. This can be really helpful for debugging and fine-tuning your skill.
There are several ways to test an Alexa Skill, including deploying it and testing it using the test interface on Alexa Developer Console, or testing it directly on your Echo devices or the Alexa Mobile App.
Testing and Deployment
Testing an Alexa Skill is a straightforward process. You can deploy the Skill and test it using the test interface on Alexa Developer Console.
There are several ways to test an Alexa Skill, including using the test interface on the Alexa Developer Console, testing it directly on your Echo devices or the Alexa Mobile App, and routing all Skill calls to your computer's console logs for debugging.
To deploy changes to your Skill, simply make a git commit and push them to the remote repository with a git push origin master. You can also merge your branch into the prod branch and deploy the code directly to the live environment, which is equivalent to clicking Promote to live in the Code tab of the developer console.
Perform Beta Testing
Perform beta testing is a crucial step when building an Alexa Skill. It allows you to validate how your Skill is performing away from controlled environments.
You can enable beta testing by going to the Distribution tab of the Developer Console. There, you'll see the Availability section on the left-side menu, where you can activate the Beta Test section.
To add beta testers, enter their email addresses in the list provided. As the Beta Test Administrator, you'll receive an email notification once you've enabled beta testing.
Your testers will receive an email with the next steps to enable the Skill. This is a great way to get real user feedback and identify any issues before releasing your Skill to the public.
To deploy your Skill to beta testers, you'll need to have them authenticate using the same Amazon Developer account as your Echo devices or the Alexa Mobile App.

Deploy

Deploying your Alexa Skill is a straightforward process. Just make a git commit and push the changes to the remote repository with a simple git push origin master.
You can also merge your branch into the prod branch and deploy the code directly to the live environment. This action replaces the live code for your published Skill, affecting the live behavior of the Skill.
Before deploying, take the time to review the submission checklist for the Alexa Skill store. This will give you peace of mind that the final Skill certification process will go smoothly.
Watch for Readiness Notification
It only takes a few minutes until your new Alexa skill is ready to go. Look for the notification message indicating the skill is available and ready to use.
You can also check the Skills You've Made link at the top of the screen. It lists all skills created with blueprints.
Once you see that your skill is Ready to Use and Edit under details, you can go ahead and launch the skill.
Certification and Launch
After testing your Alexa Skill with beta testers, it's time to submit it for certification. This process can take from a couple of hours to a full week, depending on the complexity of your Skill.
Go to the Developer Console for the Alexa Skill you built and open the Certification tab. Click Validation and run the test to ensure everything is in order. If you face any issues, fix them immediately, as it's a requirement for certification.
Add a version message to keep track of changes made to your Skill. This message is not public-facing, so don't worry about making it fancy. Once you've added the message, click Submit for review.
Once approved, your Skill will be added to the public Alexa Skills store on Amazon's website. This can take a few hours, so don't worry if it's not there immediately.

Accessing Amazon
To access Amazon, you'll need to set up an Amazon Developer account, which is free and easy to create.
Amazon provides a Developer Console where you can create, test, and manage your Alexa skills.
You'll need to provide some basic information, such as your name and email address, to get started.
To access the Developer Console, go to developer.amazon.com and sign in with your Amazon account credentials.
Once you're logged in, you can click on the "Create a new skill" button to start building your Alexa skill.
Configure Your
The invocation name is a crucial part of your Alexa Skill, it's the name required to trigger a custom Skill's intents. For example, "Daily Horoscopes" is the invocation name in the phrase "Alexa, ask Daily Horoscopes the horoscope for Gemini".
You'll want to customize your invocation name to match your Skill's purpose and branding. It's also essential to note that invocation names can be quite long, but it's recommended to keep them concise for better user experience.
The Alexa developer console includes helpful documentation for each of the elements of the voice user interface (VUI). You can find more information on invocation names, intents, and other VUI elements in the console.
Here's a summary of the most important elements of the VUI:
- Invocation name: The name required to trigger a custom Skill's intents.
- Intents: Actions that fulfill a user's spoken request.
You can also use intents with slots, which are used to capture specific information from the user's request. For example, the intent "horoscope" with the slot "Gemini" can be triggered by the phrase "Ask the horoscope for Gemini".
Define Intents and Utterances
Defining intents and utterances is where the magic happens in building a great Alexa Skill.
Utterances are recognized phrases that may be part of a sentence someone might say, and Alexa tries to match a whole sentence a user says with one utterance.
Each utterance needs to map to an intent, otherwise an unavailable intent exception is raised. An intent represents what information the user is trying to get from the Skill.
For example, a food delivery Skill might have “check menu” and “place order” intents. Utterances trigger intents.
In the Hello World project, “hello” and “say hi world” are utterances that trigger the HelloWorldIntent. You can also use keywords in the sentence, or slot values, to customize a Skill even further.
To test your Skill, enter a sample utterance in the Service Simulator, like “Say hello world.” On the right, you should see the output from the Lambda function you created.
Build
To build your custom Alexa skill, you'll need an Amazon Developers Services (ADS) account, which is free and easy to create.
First, set up your account by going to the Amazon Developers platform. If you don't have an ADS account, now is the time to create one.
To build your custom skill, you'll need to click on the "Alexa Skills Kit" and then click the "Create Skill" button to open the "Create a new skill" form.
