Serverless Alexa Skill Example

This example demonstrates how to setup your own Alexa skill using AWS Lambdas.

Use-cases

Building custom Alexa skills

How it works

In the Alexa Developer Portal you can add your own skill. To do so you need to define the available intents and then connect them to a Lambda. You can update and define the Lambda with Serverless.

Setup

In order to deploy the endpoint simply run

serverless deploy

The expected result should be similar to:

Serverless: Packaging service...
Serverless: Uploading CloudFormation file to S3...
Serverless: Uploading service .zip file to S3 (378 B)...
Serverless: Updating Stack...
Serverless: Checking Stack update progress...
.........
Serverless: Stack update finished...
Serverless: Removing old service versions...

Next we need to setup an Alexa skill. Once you've signed up for the Amazon Developer Platform visit https://developer.amazon.com/edw/home.html. There you should see the following screen:

Next click on Add a new Skill:

Go through the steps and fill in all the required fields e.g. Intent Schema and Sample Utterances:

Intent Schema

{
  "intents": [
    {
      "intent": "GetLuckyNumbers",
      "slots": [
        {
          "name": "UpperLimit",
          "type": "AMAZON.NUMBER"
        }
      ]
    }
  ]
}

Sample Utterances

GetLuckyNumbers what are my lucky numbers
GetLuckyNumbers tell me my lucky numbers
GetLuckyNumbers what are my lucky numbers lower than {UpperLimit}
GetLuckyNumbers tell me my lucky numbers lower than {UpperLimit}
