Integration of SUSI AI to Alexa

An Alexa skill which can be used to ask susi for answers like: “Alexa, ask susi chat who are you” or “Alexa, ask susi chat what is the temperature in berlin”.

If at any point of time, you are unclear about the code in the blog post, you can check the code of the already made SUSI Alexa skill from the susi_alexa_skill repository.

Getting Started : Alexa Susi AI Skill

Follow the instructions below:

Visit the Amazon developer site and Login.

Click Alexa, on the top bar.

Click Alexa skills kit.

Click on add a new skill button on the top right of the page.

We will be at the skill information tab.


Write the name of the skill Write the invocation name of the skill i.e. the name that will be used to trigger your skill. Like in our case, if we need to ask anything (as we have ‘susi chat’ as the invocation name), we will ask with “Alexa, ask susi chat” as a prefix to our question sentence.

By clicking next, we will be redirected to the second tab i.e. Interaction model. We need to fill two fields here i.e. intent schema and sample utterances. For intent schema, we need to write all the available intents and the parameters for each of them. Like in our case:

     "slots": [
         "name": "query",
         "type": "AMAZON.LITERAL"
     "intent": "callSusiApi"

We have a single intent that is “callSusiApi” and the parameter it accepts is “query” of type “AMAZON.LITERAL” (in simple words, a string type). Parameters are termed as slots here. The different types of slots available, can be seen from here.

For sample utterances, we need to tell what utterances by the client will lead to what intent. In our case:

We have just one intent and the whole string uttered by the client should be fed to this intent as a “query” slot (parameter).

Let’s click next now.

We will be shifted to the configuration tab.

We will be making a lambda function, which will hold the code for our Susi skill, further we need to link that code to this skill. To do the linking we need to get the Amazon resource name i.e. ARN and fill it in the field named endpoint:

To get the amazon resource name, in a new tab, visit here. Visit “Lambda” followed by get started button. Click on “Create a lambda function”:

We need to select a blueprint for our lambda function. Select the “blank function” option for that.

Click next.

For configure triggers option, click this box and select “Alexa skills kit” option.

Click next.

In configure function tab, just write the name of the function and its description. Let’s code our lambda function:

// basic syntax that should be available in the lambda function
var https = require('http');
exports.handler = (event, context) => {
  try {
    if ( {
      // New Session
      console.log("NEW SESSION")
    switch (event.request.type) {
      case "LaunchRequest":
        // Launch Request
        console.log(`LAUNCH REQUEST`)
            buildSpeechletResponse("Welcome to a Susi Skill, this is an A.I. chatbot developed by Fossasia open source community. Ask anything to me like temperature at a place or rating of a movie or any other thing which you would like to ask?", false),
      case "IntentRequest":
        // Intent Request
        console.log(`INTENT REQUEST`)

        switch( {
          case "callSusiApi":
            var endpoint = ""+event.request.intent.slots.query.value; // ENDPOINT GOES HERE
            var body = ""
            https.get(endpoint, (response) => {
              response.on('data', (chunk) => { body += chunk })
              response.on('end', () => {
                var data = JSON.parse(body)
                // fetching answer from susi
                var viewCount = data.answers[0].actions[0].expression;
                if(viewCount.indexOf('I found this on the web') != -1)
                    viewCount = 'I have no idea about it, sorry.';
                    buildSpeechletResponse(`${viewCount}`, false),

            throw "Invalid intent"

      case "SessionEndedRequest":
        // Session Ended Request
        console.log(`SESSION ENDED REQUEST`)
      default:`INVALID REQUEST TYPE: ${event.request.type}`)
  } catch(error) {`Exception: ${error}`) }

// Helpers
buildSpeechletResponse = (outputText, shouldEndSession) => {
  return {
    outputSpeech: {
      type: "PlainText",
      text: outputText
    shouldEndSession: shouldEndSession

generateResponse = (speechletResponse, sessionAttributes) => {
  return {
    version: "1.0",
    sessionAttributes: sessionAttributes,
    response: speechletResponse

Paste this code into the space given below “lambda function code”. In lambda function handler and role, Click the field named role and select “create a custom role” from the dropdown shown.

You will be redirected to a new page. Select the IAM role as lambda_basic_execution:

Click allow button in the bottom right. We will be redirected back to our previous page. We don’t need to worry about other settings on this page.

Click next.

Again cross-check the details shown and click next.

Now we will have our ARN (Amazon resource name) on the top right of the page.

Copy that and paste it into the field “endpoint” on our previously open browser tab:

Click next.

Great that our SUSI AI skill is ready!

Now we can test it with a sample query, when we get redirected to the test tab:

Also we can test it using our voice through reverb app available on play store or echosim by logging into your amazon account.

Till now, the skill can just be invoked or tested from your own amazon id. To make this skill public , you need to fill the other 2 tabs left that are “publishing information” and “privacy and compliance”.

Some sample strings that we can speak to test it: “Alexa, ask susi chat where are you” “Alexa, ask susi chat tell me a joke” “Alexa, ask susi chat what is a table” (where ‘susi chat’ is the invocation name).

This was the video that helped a lot in making this skill for Alexa. It can be referred too.
